In the building construction process, the influence of the buoyancy of the underground water on the building or the structure needs to be considered under some conditions, the structure is damaged due to the overlarge buoyancy, however, in the related technology, the treatment measures are often carried out under the condition that the solid structure is damaged, the structure safety cannot be early warned, and the construction efficiency is low.
In order to pre-warn the structural safety of a building or a structure and improve the construction efficiency, the embodiment of the disclosure provides a pre-warning method, and the pre-warning water level is set by establishing the relation between the safety and reliability of the building and the underground water level, so that the pre-warning effect on the safety of the building or the structure is achieved, and the pre-warning method has higher application value.
The method of the embodiment of the present disclosure may be implemented by embedding an insert in modeling software such as autodesk revit14, where a specific form of the modeling software is not limited, and the method of the embodiment of the present disclosure may be implemented by the insert, and a user may pre-build a building information model (Building Information Modeling, BIM) for simulating a building construction process, and may begin to implement after the building.
Fig. 1 shows a flow chart of an early warning method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:
step S101, calculating the reliability of the building or the structure to be built under the plurality of historical ground water levels according to the plurality of historical ground water levels of the target position of the building construction site.
Because different construction stages exist in the construction site, the target position of the construction site is determined according to the corresponding building or structure to be constructed in the different construction stages, the target position can be a preset position in the different construction stages, and the preset position and the construction stage can all comprise various types, and the description is omitted herein in detail in the possible implementation manners disclosed in the following text.
The historical ground water level can be obtained from the existing ground water level data, can be the ground water level on the history of the target position, can be the ground water level on the history of the position similar to the terrain, can also be the ground water level on the history near the target position, and is not limited herein.
Because the building or structure to be built is often affected by the groundwater level, under different groundwater levels, the safety, applicability and durability of the building or structure to be built may be different, and these performances of the building or structure may be represented by the reliability, in the embodiment of the disclosure, the reliability of the building or structure to be built under different historical groundwater levels may be calculated according to the target position and the corresponding historical groundwater level, and the performances of the building or structure to be built on the construction site may be measured by the reliability.
The reliability calculation method may include a Monte Carlo algorithm, a response surface method, a multiple multi-order moment method, and the like.
Step S102, taking the historical underground water level corresponding to the target reliability as an early warning water level;
the reliability of the building or the structure to be built under a plurality of historical groundwater levels is obtained through calculation in the step S101, and the reliability can reflect the performance of the structure to be built, so that early warning can be performed under the condition that the reliability reflects the performance of the building or the structure to be affected, so that staff can take corresponding measures, and particularly early warning can be performed by defining at least one early warning level. For convenience of description, the reliability used to define different pre-warning levels is referred to herein as target reliability, which may be considered as a threshold for different pre-warning levels.
For example, the possible mapping relationship between the reliability and the early warning water level may be represented as a reliability a-historical water level a, a reliability B-historical water level B, and a reliability C-historical water level C, and if the reliability is lower than B, the performance of the building or structure may be affected, and then the target reliability may include the reliability B, and the corresponding early warning water level is B.
Step S103, determining the corresponding relation between the early warning water level and the early warning level according to the corresponding relation between the target reliability and the early warning level and the corresponding relation between the target reliability and the early warning water level;
as described above, the target reliability is used to define the pre-warning level, and the pre-warning level of the target reliability is obtained in step 102, then the pre-warning level may be defined by the pre-warning level. Through the corresponding relation between the early warning water level and the early warning level, the early warning level can distinguish different influences of different early warning water levels on structural performance.
And then, the predicted water level at a certain moment in the future can be compared with the early-warning water level by taking the early-warning water level as a definition standard for measuring whether the building or the structure is reliable or not, so that the effect of carrying out safety early warning on the performance of the building or the structure to be built at a target position at a certain moment in the future is realized. So as to take countermeasures in advance, reduce the influence of the groundwater level on the performance of the building or the structure, improve the construction efficiency and reduce possible economic loss.
According to the embodiment of the disclosure, the reliability can accurately measure the structural safety of the building to be built, so that the structural safety of the building to be built can be accurately reflected through the early warning water level by utilizing the data of the historical underground water level and determining the mapping relation between the reliability and the early warning water level; through the mapping relation between the pre-warning water level and the pre-warning level, the possible influence of different underground water levels on the safety of a building or a structure is divided into a plurality of levels, so that the pre-warning of the underground water level safety is more hierarchical, the possibility of occurrence of related accidents is further reduced, and the possible economic loss is reduced.
Fig. 2 shows a flow chart of an early warning method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
step S201: predicting the underground water level of a target position of a building construction site to obtain a predicted water level;
the predicted water level is a water level in the future of the target position obtained by prediction, and may be, for example, a water level daily for 15 days in the future, or a water level daily for a week.
The predicted water level may be determined from a plurality of parameters according to preset conditions, and the preset conditions may also include a plurality of types, which will be specifically described in a possible implementation manner of the disclosure of the following text, and are not described herein in detail.
Step S202: comparing the predicted water level with the early warning water level, and determining an early warning level corresponding to the predicted water level according to a comparison result;
the early warning water level corresponds to target reliability representing different early warning levels, and the target reliability comprises the reliability of a building or structure to be built under the condition that the underground water level at the target position is the early warning water level. Specifically, the target reliability may define different pre-warning levels, and the pre-warning levels and the target reliability corresponding to the pre-warning levels may be determined according to the method in the foregoing embodiment as critical points of the different pre-warning levels, which is not described herein.
Ground level may refer to the height of the ground surface relative to a reference surface, typically expressed in absolute elevation. That is, the ground water level is lowered, and the larger the height of the ground water surface with respect to the reference surface is, the larger the value of the ground water level is; the lower the level of the ground water relative to the datum level, the lower the value of the ground water, the more likely the building or structure and/or anti-floating device will be damaged.
Specifically, if the early-warning water level is 6 meters corresponding to the red early-warning level (can be the highest early-warning level), 8 meters corresponding to the orange early-warning level, 10 meters corresponding to the yellow early-warning level, and 12 meters corresponding to the blue early-warning level, the predicted water level is compared with the early-warning level. If the early warning water level is between 10 meters and 12 meters, corresponding blue early warning is carried out, and corresponding measures of the blue early warning are carried out; if the early warning water level is between 8 meters and 10 meters, corresponding yellow early warning is carried out, and corresponding measures of the yellow early warning are carried out; if the early warning water level is between 6 meters and 8 meters, corresponding orange early warning is carried out, and corresponding measures of the orange early warning are carried out; and if the early warning water level is higher than 6 meters, corresponding red early warning is carried out, and corresponding measures of the red early warning are carried out.
The early warning level is used for distinguishing different influences on structural safety under different early warning water levels.
Step S203: and executing the early warning measures corresponding to the early warning grades.
The early warning measures and the early warning levels have corresponding relations, and as described above, the early warning levels can distinguish different influences of different early warning water levels on structural performance, and the corresponding early warning measures formulated for the different influences can reduce possible influences of the underground water levels on the performance of a building or a construction, so that the early warning effect is achieved.
Meanwhile, the early warning level and the corresponding early warning measures can be adjustable, and after the early warning measures are executed, the early warning level and the early warning measures can be adjusted according to the specific conditions of the construction project site, and the details of the early warning level and the early warning measures are described in a possible implementation mode of later text disclosure and are not repeated here.
According to the embodiment of the disclosure, the groundwater level is predicted, so that the randomness of the groundwater level caused by uncertain factors such as weather and the like can be considered in advance, and meanwhile, the reliability can accurately measure the structural safety of the building to be built, so that the early warning water level determined based on the reliability can more accurately early warn the structural safety of the building to be built; then, the predicted water level is compared with the early warning water level, so that the structural safety of the building to be built can be intuitively confirmed through the comparison result; by executing the early warning measures, the related conditions of the construction site are prevented in advance, so that related accidents possibly occurring can be reduced as much as possible, the efficiency of the construction site is improved, and possible economic losses are avoided.
In the embodiment of the disclosure, various implementation manners of the early warning method may be provided.
In one possible implementation, the method is applied to a preset time node of a construction project, where the building or structure to be constructed includes the building or structure to be constructed, and the preset time node includes at least one of the following: before the construction project begins to construct; a target construction stage in construction project construction.
The preset time node applied by the method can be any time node or time stage of a construction project, and the target construction stage can refer to any construction stage in the construction project. Because the buildings or structures to be constructed of the construction project can be different under different time nodes, the reliability of the target position can be different under the different time nodes, so that the target position under the different time nodes is different, and therefore the early warning water level has a corresponding relation with the preset time node.
Specifically, the target construction stage may include: the basement bottom plate is finished but not connected into a whole; finishing the basement locally, namely finishing the column, the roof beam and the roof of the basement; the basement is connected into a whole; and (5) completing earthing. Different pre-warning water levels can be corresponding to different pre-set time nodes for comparison of subsequent pre-warning so as to realize the function of safety pre-warning on the performance of a building or structure to be built at a target position at a certain moment in the future.
In one possible implementation, the method further includes: after an accident occurs to a built building or structure due to the underground water level, determining the first reliability of the building or structure under construction according to the historical highest water level and the historical highest water level; from said first reliability, a second reliability is determined, which may be reliability without damaging the building or structure and/or the anti-floating device at the highest historic water level, due to the need to repair and/or reset the anti-floating device at the built building or structure.
Performing a processing measure according to the second reliability, the processing measure comprising: a building or structure and/or anti-float device structure is provided that meets the second reliability. So that the worker repairs or resets the anti-floating device on the constructed building or structure according to the provided structure or structure and/or anti-floating device structure to improve the anti-floating stability of the constructed building or structure.
The anti-floating device can comprise anti-floating piles, anti-floating anchor rods and the like, after an accident occurs, the first reliability of the building or the structure calculated according to the highest historical water level can be used for evaluating the state of the building or the structure with the accident and implementing corresponding treatment measures.
In one or more possible implementations provided by the present disclosure, the reliability is related to the groundwater level and a specific structure of a building or a structure, and may be specifically obtained by calculating a functional function of the groundwater level and the building or the structure, please refer to formula (1), which is an implementation manner of calculating the reliability provided by the present disclosure:
wherein P is f Representing the failure probability of anti-floating and sinking;cumulative distribution function for standard normal random variables, < >>The value of (2) can be derived from formula (2):
wherein, beta represents the anti-floating reliability of the structure, and the value of beta can be obtained by the formula (3):
wherein Z represents the anti-floating function of the structure, mu Z Anti-floating functional function of representing structureThe mean value of the numbers, that is, the average level of the structural anti-floating function; sigma (sigma) Z The standard deviation of the anti-floating function of the structure is represented, namely the discrete degree of the anti-floating function of the structure, and the larger the standard deviation is, the more discrete the data distribution of the anti-floating function of the structure is; alpha 3Z The deviation coefficient of the anti-floating function of the structure is represented, namely, the degree of symmetry of the data of the anti-floating function of the structure is closer to 0, the deviation coefficient is more symmetrical, the more far from 0 is the description data is more asymmetrical, the deviation coefficient is positive, the data is right-deviated, and the data is left-deviated when the deviation coefficient is negative; alpha 4Z The kurtosis coefficient of the anti-floating function of the structure is represented, namely the steepness or smoothness degree of the data distribution of the anti-floating function of the structure relative to the normal distribution is that the closer the kurtosis coefficient is to 0, the more the kurtosis of the data distribution is compliant to the normal distribution, the kurtosis coefficient is greater than 0, and the kurtosis of the data distribution is steep (high-pointed); kurtosis coefficient is less than 0, and the kurtosis of the distribution is gentle (short and fat).
μ Z 、σ Z 、α 3Z 、α 4Z The values of (a) can be obtained from the formulas (4), (5), (6) and (7), respectively:
wherein h (theta) represents a function, which is a hidden function; θ represents a vector space composed of structural parameters affecting reliability such as historic ground water level, material properties, cross-sectional dimensions, and the like, and is expressed as θ= (θ) 1 ,θ 2 ,θ 3 ,...θ i ) T ;w i And theta i (i=1, 2,3 … d) each represents a constant weight and an integration point in the d-dimensional infinite area, i represents the number of integration points in the d-dimensional infinite area, and each h (θ i ) The function value of θ can be calculated from i Leading into finite element software for calculation; f (f) Θ (θ) represents a joint probability density function, which can be represented by θ i Is multiplied by a probability density function of (c).
Through the formulas (1) - (7), the reliability of the building or the structure under the underground water level can be accurately obtained, in the embodiment of the disclosure, the reliability corresponding to the underground water level is calculated, the limit state of the bearing capacity of the building or the structure at the preset time node of the construction project can be given clearly, the anti-floating limit capacity of each stage can be given clearly, the design and construction management can be guided well, and the method can be applied to similar projects after standardization.
The following takes specific data of a large underground garage underground water safety accident under construction, which is located at two sides of the Changshaxiang river as an example, and specifically describes a calculation process based on the reliability of underground water and the influence of the reliability on construction safety:
working conditions are classified according to time periods and construction stages, wherein the working conditions can be preset time nodes as described above, and classification results are shown in table 1:
TABLE 1 working condition classification
The specific calculation results of each parameter in the reliability calculation process under each working condition are shown in table 2:
table 2 calculation results
Reliability rules in accordance with the unified standards for building Structure reliability design (GB 50068-2001) in Table 3:
TABLE 3 ultimate state reliability of structural member bearing capacity
The corresponding relation diagram of the working condition and the reliability shown in the figure 3 can be obtained, the project has a second safety level, the reliability is defined to be smaller than the limit value according to the bearing capacity limit state of the structural member according to the calculated result and the corresponding relation diagram, and the anti-floating failure probability P in rainy season construction is shown only if the reliability beta of the working condition A-3 is 4.95 and meets the standard requirement f Higher, the ground water safety accident is likely to happen, and the water level condition should be strictly controlled. Meanwhile, in the accident period, the negative layer of the building structure is finished, the anti-floating failure probability of the structure is smaller when the working condition B-2 is used for calculating the underground water level, the anti-floating failure probability of the working condition B-4 is very large under the condition of actually measuring the water level on site, the large failure probability is not allowed under the reasonable design condition, the underground water safety accident actually occurs in the actual engineering at the stage, and the actual water level change and the underground water level change can be verified to be asynchronous. The reason for this problem is that the soil covering is not completed in the accident period, the groundwater level is accelerated and stays high due to the surface water filling, and the foundation stratum is impermeable to water, so that a foot basin effect is generated, and the drainage difficulty is increased.
Meanwhile, in different time periods, the reliability change of each construction stage is obvious, particularly under the condition of earthing, the earthing can ensure the increase of the dead weight of the upper part in the anti-floating process so as to strengthen the anti-floating capability, and meanwhile, the surface water is not poured, and the reliability of A-3 and B-3 displayed in calculation is greatly changed in comparison with the time period.
The anti-floating failure probability under each working condition can be obtained by processing the reliability calculation result under each working condition, so that the problems about anti-floating water level, groundwater safety early warning measure selection in the construction period and field management can be more intuitively analyzed, the groundwater safety in the whole construction period can be better estimated, and more definite guidance is provided for groundwater safety early warning.
In the embodiment of the disclosure, the reliability is converted into the early warning water level, so that the early warning water level intuitively reflects the reliability of the structure to be built, and the reliability is not required to be calculated in the early warning process, thereby improving the early warning efficiency. In addition, the future underground water level is predicted, so that early warning is carried out on the safety of the building or the structure in advance, and accordingly constructors can take anti-floating measures in advance in the future building of the building or the structure to be built, and the safety in the construction process is improved.
