In order to further describe the technical means and effects adopted by the present invention to achieve the preset purposes, the following detailed description refers to the specific implementation, structure, characteristics and effects of a construction quality management system for a building construction project according to the present invention with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" means that the embodiments are not necessarily the same. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The following specifically describes a specific scheme of a construction quality management system for a building construction project provided by the invention with reference to the accompanying drawings.
Referring to fig. 1, a system block diagram of a construction quality management system for a building construction project according to an embodiment of the present invention is shown, where the system includes a data acquisition module, an external impact index acquisition module, an index weight acquisition and quality management module:
the data acquisition module is used for setting each evaluation index and acquiring the monitoring value of each evaluation index of each foundation pile in the construction site and the drilling machine power corresponding to each moment of each foundation pile in the construction time period.
The stability of the foundation influences the engineering quality of building projects, the pile foundation project is a construction project which strengthens the stability of the foundation through pile foundations and prevents the construction from being inclined due to uneven settlement, and the foundation pile foundation is widely applied to various building projects. In pile foundation projects, parameters such as pile position selection, depth of foundation piles (namely pile depth), slurry flow of reinforced cement slurry, inclination angle of pile holes, ground hardness of construction ground and the like are key parameters in the construction process of the pile foundation projects.
In this embodiment, various sensors are used to obtain the above parameters of the pile foundation project, and a specific obtaining method is as follows: the pile position is obtained through a high-precision positioning system, such as a Beidou positioning system; the pile depth can be obtained by utilizing the sliding travel of a pile driver steel cable, and a photoelectric encoder is arranged on a pile driver frame to monitor the pile depth in real time; the mud flow is obtained by an electromagnetic flowmeter; the inclination angle of the pile hole is determined by a drilling machine, and an angle sensor is arranged on a drill rod rack so as to acquire an inclination angle parameter; the ground hardness of the construction ground can be reflected through the power of a drilling machine and the construction time, namely, for the ground with the same size, the larger the power of the drilling machine is, the longer the construction time is, the larger the ground hardness of the corresponding construction ground is, in the embodiment, the ground hardness of the corresponding position of each foundation pile is estimated through the power of the drilling machine and the construction time of the drilling machine corresponding to each moment in the construction process of each foundation pile, wherein the output quantity of a photoelectric encoder corresponds to the pile depth, the output current of an electromagnetic flowmeter corresponds to the slurry flow, the output quantity of an angle sensor corresponds to the inclination angle of the foundation pile, the output quantity of different sensors is the monitoring value of the corresponding construction parameter, and the reading of the output quantity of the sensors is known technology, and is not repeated in detail.
The construction parameters such as pile position, pile depth, slurry flow, inclination angle and ground hardness of a pile foundation project in building construction are monitored in real time, so that the quality of the current construction project is estimated, all the construction parameters monitored in real time are simply called all the monitoring parameters, the construction quality of each foundation pile after construction is completed is estimated integrally, when the construction quality is reduced, the fact that the current foundation pile causes the construction quality to be reduced is indicated, a certain potential safety hazard exists in the construction project, at the moment, secondary construction is needed to be carried out on the current foundation pile until the construction quality of the current foundation pile reaches the quality standard, and the fact that the first foundation pile is constructed according to manual experience is needed to be explained;
the hardness of the ground is different in different places in the building construction process, so that the pile position is selected, the depths of foundation piles are different, the depth and the position of each foundation pile are also different in the construction process, the slurry water quantity and the inclination angle required by the foundation piles with different depths are also different, for example, the construction power of a drilling machine is higher when the hardness of the construction ground is higher, and the inclination angle is harder to control; in a certain area, the more dense the pile positions, namely the more the number of foundation piles, the more important the area is in the building construction project or the poorer the stability of the foundation of the area is; that is, there is a interplay between different monitored parameters;
in addition, as only the ground hardness of the construction site is the self characteristic of the construction site in each monitoring parameter, other monitoring parameters such as pile position, pile depth, slurry flow, inclination angle and the like can be correspondingly changed due to the difference of the ground hardness, so that the mutual influence among the monitoring parameters is essentially the influence of the ground hardness on the other monitoring parameters; however, since the pile position is often required to be predetermined, and the difference formed by the influence of the ground hardness is relatively fixed, the pile depth, the slurry flow and the inclination angle of the foundation pile can have a great influence on the construction quality in the actual construction process, so in the embodiment, the pile depth, the slurry flow and the inclination angle of the foundation pile are used as all evaluation indexes of the construction quality, the monitoring value corresponding to each evaluation index of each foundation pile is the output value of the corresponding sensor after the construction of each foundation pile is completed, and each evaluation index corresponds to 4 evaluation grades, namely, excellent, good, medium and poor; the hardness of the ground is taken as an external influence factor.
The external influence index acquisition module is used for taking any foundation pile in a construction site as a target foundation pile, and obtaining the ground hardness difference of the target foundation pile according to the drilling power of each foundation pile in the target foundation pile and the peripheral area; obtaining the index difference significance of the target foundation piles according to different evaluation indexes of the target foundation piles and each foundation pile in the peripheral area; and obtaining the external influence index of the target foundation pile according to the ground hardness difference and the index difference significance of the target foundation pile, and obtaining the external influence index of each foundation pile in the construction site by taking each foundation pile in the construction site as the target foundation pile.
When the index weight of each evaluation index is calculated by using the fuzzy evaluation method, the influence among different evaluation indexes also has an influence on the calculation of the index weight, so that the embodiment obtains the fuzzy comprehensive evaluation conforming to the actual construction site by using the mutual influence among different monitoring parameters. According to building specifications and experience of constructors, a standard value and a reference range which accords with quality standards are given to each construction parameter, and a quality evaluation result is obtained by comparing the real-time monitoring result with the reference range; the reference ranges corresponding to the different evaluation levels of the different evaluation indexes are as follows:
the reference range of the evaluation grade corresponding to the pile depth D is sequentially as follows

The standard value of the pile depth, the standard value of the slurry flow rate, and the standard value of the inclination angle in this embodiment are known values which have been determined before project construction, and are determined according to project construction standards.
Taking pile depth as an example:
the meaning of the method is that the ratio of the current monitoring value to the standard value is more than or equal to 0.98, which indicates that the pile depth of the construction site reaches the construction quality standard at the moment and the evaluation grade is excellent;
the meaning of the method is that the ratio of the current monitoring value to the standard value is more than or equal to 0.95 and less than 0.98, which indicates that the pile depth of the construction site reaches the construction quality standard and the evaluation grade is good;
the meaning of the method is that the ratio of the current monitoring value to the standard value is more than or equal to 0.92 and less than 0.95, which indicates that the pile depth of the construction site just reaches the construction quality standard at the moment, and the evaluation grade is middle;
the meaning of the method is that the ratio of the current monitoring value to the standard value is smaller than 0.92, which indicates that the pile depth of the construction site does not reach the construction quality standard at the moment, and the corresponding evaluation grade is poor; the meaning of each reference range corresponding to other monitoring parameters is similar, and the repeated description is omitted.
In this embodiment, a set of evaluation indexes is referred to as an evaluation index set U of a building construction project; the set of 4 evaluation grades of excellent, good, medium and bad is called an evaluation grade set V of building construction projects, wherein the evaluation index set
The evaluation grade set is V= { excellent, good, medium and bad }, each foundation pile can obtain the monitoring value of each evaluation index, wherein for the u-th evaluation index in the evaluation index set, the monitoring value corresponding to the a-th foundation pile is
；
In this embodiment, the ground hardness is taken as an external influence factor, and the external influence index of each foundation pile is obtained according to the difference of the ground hardness of each foundation pile and the foundation piles in the peripheral area thereof and the significance of the index difference, so as to represent the influence degree of each evaluation index of each foundation pile by the external influence factor of the construction site, wherein the a-th foundation pile is taken as an example, the a-th foundation pile is taken as a target foundation pile, the peripheral area of the a-th foundation pile is a square with the a-th foundation pile as the center and the preset length r as the side lengthIn the region, r is set to 3 m in this embodiment, the external influence index of the a-th foundation pile
Can be expressed as:
in the method, in the process of the invention,
the difference of the hardness of the ground for the a-th foundation pile;
index difference significance for the a-th foundation pile; j is the j-th foundation pile in the peripheral region of the a-th foundation pile; n is the number of foundation piles contained in the peripheral area of the a-th foundation pile;
is the drilling power of the j-th foundation pile at the t-th moment in the construction period of the j-th foundation pile,
at a T-th moment in the construction time period of an a-th foundation pile, the drilling power of the a-th foundation pile, T refers to the length of the construction time period of the a-th foundation pile; u represents the U-th evaluation index in the evaluation index set U,
is a monitoring value corresponding to a ith evaluation index of the jth foundation pile;
is a monitoring value corresponding to the u rating index of the a foundation pile;
is the number of evaluation indexes included in the evaluation index set U, and in this embodiment
The value of (2) is 3,e, which is a natural constant, and the magnitude of e is 2.7.
the difference between the ground hardness of different positions can cause the difference between other evaluation indexes of foundation piles at different positions, when the absolute value of the difference between the same evaluation indexes of the a foundation pile and other foundation piles in the peripheral area is larger, namely the difference between the same evaluation indexes of the a foundation pile and other foundation piles in the peripheral area is larger, the larger the influence of the ground hardness on the a foundation pile is indicated, namely the larger the influence of the external influence factor on the a foundation pile is indicated, otherwise, the smaller the influence of the external influence factor on the construction quality of the a foundation pile is indicated, namely the influence of the external influence factor on the a foundation pile is less obvious, so that the difference between the different evaluation indexes of the a foundation pile and each foundation pile in the peripheral area is analyzed to obtain the index difference significance of the a foundation pile.
Finally, the influence degree of the external influence factors on each foundation pile is analyzed by combining the ground hardness difference of the peripheral area of each foundation pile and the influence degree of the difference between different ground hardness on each evaluation index, namely, the external influence index of each foundation pile is obtained according to the index difference significance of each foundation pile and the ground hardness difference; taking each foundation pile in the construction site as a target foundation pile to obtain an external influence index of each foundation pile in the construction site;
the index weight acquisition module takes any one evaluation index as a target evaluation index, and obtains the interference degree corresponding to the target evaluation index of each foundation pile according to the external influence index of each foundation pile in the construction site and the monitoring value corresponding to the target evaluation index of each foundation pile; obtaining the influence duty ratio corresponding to the target evaluation index of each foundation pile according to the interference degree corresponding to the target evaluation index of each foundation pile; obtaining interference information entropy of the target evaluation indexes according to the influence duty ratio corresponding to the target evaluation indexes of all foundation piles; taking each evaluation index as a target evaluation index to obtain interference information entropy of each evaluation index; and obtaining the index weight of each evaluation index according to the interference information entropy of each evaluation index.
In the fuzzy comprehensive evaluation method, the statistics of the membership matrix R is the fuzzy relation between each evaluation index and each evaluation grade, the membership matrix R is obtained through a trapezoid membership function, the calculation process of the membership matrix is a known technology, and the details are not repeated here, wherein the elements of the ith row and the ith column in the membership matrix are the elements of the fifth row and the sixth column
Representing the membership degree of the ith rating index in the rating index set U to the ith grade in the rating grade set V; in this embodiment, the evaluation index set includes three evaluation indexes, and the evaluation grade set includes four evaluation grades, so that the obtained membership matrix is a 3×4 matrix, and in the fuzzy comprehensive evaluation method, the index weight refers to the influence degree of each evaluation index in the rating index set U on the evaluation result.
Because different evaluation indexes are influenced by external factors in the foundation pile construction process, an index weight suitable for the scene of the embodiment needs to be constructed, and the index weight of each evaluation index is constructed according to the external influence index of each foundation pile and used for representing the importance degree of each evaluation index; for the ith evaluation index, the product of the external influence index of each foundation pile and the corresponding monitored value of each foundation pile is taken as the influence degree of the ith evaluation index of each foundation pile, and the monitored value of the ith evaluation index after construction is completed is recorded as
The external influence index of the ith foundation pile is
The ith evaluation index of the ith foundation pile is interfered to the extent of
Then obtaining the index weight of the ith evaluation index in the evaluation index set according to the interference degree corresponding to the ith evaluation index of each foundation pile
Then:
in the method, in the process of the invention,
the influence duty ratio of the ith foundation pile and the (u) th evaluation index is the ratio of the interference degree corresponding to the ith foundation pile and the total interference degree of the ith evaluation index;
is the external influence index of the i-th foundation pile,
the monitoring value is a monitoring value corresponding to a ith evaluation index of the ith foundation pile, and m is the total number of foundation piles in the whole construction site;
is the interference information entropy of the u-th evaluation index,
is the index weight of the u-th index,
is the number of evaluation indexes included in the evaluation index set U, in this embodiment
Has a value of 3;
is a logarithmic function based on natural constants.
Influencing the duty cycle
The larger the ith foundation pile, the greater the interference degree of the ith evaluation index influenced by external factors; interference information entropy
The larger the value of the (u) th evaluation index is, the more complicated the interference degree of the (u) th evaluation index on different foundation piles is, the larger the uncertainty of the evaluation level to which the (u) th evaluation index belongs is, namely, the larger the difficulty of determining the evaluation level corresponding to the (u) th evaluation index is, and the larger the influence of the (u) th evaluation index on the construction quality is, namely, the index weight is
The larger the evaluation level of the u-th evaluation index should be, the more attention should be paid to the evaluation level of the u-th evaluation index at this time when evaluating the construction quality, whereas the more attention should be paid to the evaluation level of the u-th evaluation index.
Because the interference degree of each foundation pile by external influence factors is different, the embodiment firstly obtains the influence duty ratio of each evaluation index of each foundation pile according to the duty ratio of the interference degree corresponding to each evaluation index of each foundation pile in the total interference degree of the evaluation indexes corresponding to all foundation piles; the index weight of each evaluation index is obtained by combining the interference information entropy of the same evaluation index on different foundation piles, which is corresponding to the influence duty ratio, so that the problem that the index weight is allocated artificially and subjectively and is not matched with the construction site is avoided, and the evaluation of the construction quality corresponding to the building construction project is more matched with the actual construction condition;
the method is repeated to obtain the index weight of each evaluation index in the evaluation index set U, and the index weights of all the evaluation indexes form an index weight sequence W, wherein, since each evaluation index corresponds to one index weight, the obtained index weight sequence can be regarded as a 1×3 one-dimensional matrix, then the index weight sequence W and the membership matrix R are multiplied to obtain an evaluation result matrix a, the obtained evaluation result matrix a is a 1×4 matrix, and the matrix operation is a well-known technology and will not be described herein.
The quality management module is used for acquiring a membership matrix, obtaining an index weight sequence according to the index weight of each evaluation index, and obtaining an evaluation result matrix according to the index weight sequence and the membership matrix; and obtaining a comprehensive grading value according to the evaluation result matrix and a preset evaluation amplitude matrix, obtaining construction quality according to the comprehensive grading value, and managing building construction projects according to the obtained construction quality.
Normalizing each element in the evaluation result matrix a by using a softmax function so that the sum of the accumulated elements in the normalized evaluation result matrix a is 1, and then presetting an evaluation amplitude matrix s=
Multiplying the evaluation result matrix A by the evaluation amplitude matrix S, recording the obtained product as a comprehensive evaluation value Z, and judging the construction quality according to the magnitude of the comprehensive average value, namely
When the current construction quality is considered to be excellent; when (when)
