Description
Technical Field
The invention relates to a method for analyzing and controlling the closing time of a post-sedimentation casting strip.
Background
In the design and construction process of super high-rise buildings, one or more high-rise buildings and low-rise skirt houses are usually constructed on large-area underground buildings, and large differential settlement deformation is generated due to large difference of load and structural rigidity between the high-rise buildings and the skirt houses. Generally, the arrangement of the post-cast strip is an effective means for solving the problem of coordination between deformation of the main building and the skirt house. When the settlement of the two sides of the settlement post-cast strip tends to be stable, the closing operation of the settlement post-cast strip can be carried out. However, considering that the reserved post-cast strip can greatly affect the traffic line organization, material transportation, electromechanical arrangement, indoor decoration and the like of a construction site, the advantage of early sealing the post-cast strip is obvious from the perspective of engineering construction. It can be seen that the early closure and late closure of the settled post-cast strip are in conflict.
In the engineering construction process, the differential deformation of the main building and the post-settlement casting belt is generally monitored, and when the variation trend of the differential deformation is found to be slow, the sealing operation is carried out; however, as the main building is built for too long time, the post-cast strip is generally sealed later, which causes adverse effects on site operation, or the post-cast strip is artificially sealed early, which causes great differential deformation between the main building and the skirt house, and influences the stress state of the main building and the skirt house.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1, the present invention provides a method for analyzing and controlling a closure time of a post-sedimentation casting strip, comprising:
step S1, aiming at the construction conditions of the main building and the skirt building of the super high-rise building, carrying out finite element analysis in the construction stage based on the construction parameter values of the main building, and calculating to obtain a theoretical difference deformation curve between the settlement of the position of the main building and the settlement of the position of the skirt building under the real condition;
the method can be used for carrying out construction stage finite element analysis aiming at the conditions of main building construction and skirt building construction of the super high-rise building, and calculating a theoretical difference deformation value between the settlement of the position of the main building and the settlement of the position of the skirt building, wherein a theoretical difference deformation curve takes time as an abscissa, and a theoretical difference deformation value between the settlement of the position of the main building and the settlement of the position of the skirt building as an ordinate. The number of leading construction layers of the main building, the self weight of concrete and the like considered in the calculation are matched with the actual construction condition, and a theoretical difference deformation curve between the settlement of the position of the main building and the settlement of the position of the skirt house under the real condition is obtained. The theoretical differential deformation value between the settlement of the main building position and the settlement of the skirt room position at each time point can be extracted from the theoretical differential deformation curve between the settlement of the main building position and the settlement of the skirt room position under the real condition, and the time point can be accurate to the hour level.
The construction parameters of the main building may include: the construction floor of the main building is ahead, the concrete dead weight value of the main building and the concrete shrinkage creep value of the post-subsidence casting strip position of the main building are obtained.
Step S2, in the construction process of the main building and the current stage of the skirt house, measuring the actual differential deformation value between the settlement of the main building position and the settlement of the skirt house position in the construction process of the current stage by adopting preset equipment and a preset measuring method;
here, the measured value of the actual differential deformation value between the settlement of the main building position and the settlement of the skirt building position and the measurement time can be recorded by adopting a manual means or an automatic means;
step S3, determining a theoretical value noise variance of a theoretical difference deformation value based on a theoretical difference deformation curve between the settlement of the main building position and the settlement of the skirt building position under the real condition;
here, step S3 may include:
step S31, taking 60% -140% of the construction parameter values of the main building, taking every 10% of the construction parameter values of the main building in 60% -140% as a grade, carrying out construction stage finite element analysis based on the construction parameter values of the main building of each grade, and calculating to obtain a theoretical difference deformation curve between the settlement of the main building position of each grade and the settlement of the skirt building position;
and step S32, performing summary variance calculation on the theoretical difference deformation curve between the settlement of the main building position and the settlement of the skirt room position of each grade and the theoretical difference deformation curve between the settlement of the main building position and the settlement of the skirt room position under the real condition to obtain the theoretical value noise variance of the theoretical difference deformation value.
The noise variance is calculated by adjusting various parameters such as the number of construction floors ahead of the main building, the concrete weight of the main building, and the concrete shrinkage and creep at the position of the main building post-settlement casting strip (generally, the construction parameter value of the main building in step S1 is adjusted to 60% to 140%, and the calculation is divided into 10% per grade), and the theoretical differential deformation under the parameter adjustment results of each grade is calculated. And summarizing the theoretical difference deformation after parameter adjustment as a sample and the theoretical difference deformation sample calculated under the real condition obtained in the step S1, and calculating the variance to obtain the theoretical value noise variance. The obtained theoretical value noise variance is larger, which shows that the theoretical difference deformation calculation error is larger.
Step S4, determining a measurement noise variance of an actual difference deformation value based on the actual difference deformation value between the main building position settlement and the skirt building position settlement in the construction process of the current stage;
here, step S4 includes:
step S41, when the main building and the skirt house are both in a construction stop state, measuring the actual differential deformation value between the settlement of the main building position and the settlement of the skirt house position for a plurality of times continuously at preset intervals by adopting the preset equipment and the preset measuring method;
step S42, carrying out summary variance calculation on the actual differential deformation value between the settlement of the main building position and the settlement of the skirt room position obtained by each measurement when the main building and the skirt room are both in the construction stop state and the actual differential deformation value between the settlement of the main building position and the settlement of the skirt room position in the construction process of the current stage so as to obtain the measurement noise variance of the actual differential deformation value;
here, the noise variance is measured in step S41, and it can be obtained by using the same equipment and the same measuring method in step S2, when both the main building and the skirt building are in the construction stopped state, the measurement of the differential deformation value is continuously performed a plurality of times every one hour at a certain time interval (for example, 1 hour), and at the same time, the actual differential deformation values between the settlement of the main building position and the settlement of the skirt building position in the construction process of the current stage in step S2 are summarized, and the variance of each measurement result sample is calculated as the measured value noise variance. Here, a relatively small measurement value noise variance is obtained, which means that the measurement error of the actual difference deformation value is relatively small.
Step S5, after the main building construction and the next stage of the skirt building construction process, measuring the actual difference deformation value between the main building position settlement and the skirt building position settlement in the next stage of the construction process by adopting preset equipment and a measuring method, substituting the theoretical difference deformation curve, the measured actual difference deformation value between the main building position settlement and the skirt building position settlement in the next stage of the construction process, the theoretical value noise variance of the theoretical difference deformation value and the measured noise variance of the actual difference deformation value into a Kalman filtering formula to obtain a corrected theoretical difference deformation curve;
and repeating the step S5 after the construction process of the main building and each next stage of the skirt building is completed until the slope of the obtained corrected theoretical differential deformation curve is smaller than a preset threshold value.
After the next stage of main building construction and skirt building construction, the actual differential deformation value can be measured, the theoretical differential deformation value and the actual differential deformation value of the theoretical differential deformation curve in the step S1 are substituted into the kalman filtering formula to obtain the post-subsidence casting belt differential deformation filtered estimation value, and meanwhile, the theoretical noise variance and the measured noise variance are also substituted into the kalman filtering formula to obtain the corrected theoretical differential deformation curve.
The operation of step S5 may be repeated in each construction stage, theoretical and actual measurement corrections may be continuously performed on the differential deformation of the post-settling strip, and the determination of the closing time of the post-settling strip may be performed based on the correction data, for example, when the slope of the corrected theoretical differential deformation curve is equal to 0.
The filtering estimation variance is irrelevant to the measured value and only relevant to the noise variance, so that the filtering estimation variance can be calculated in advance, and a corrected differential deformation curve can be given in advance to serve as a judgment principle of the final sedimentation post-cast strip closing time; and meanwhile, performing curve fitting (continuous correction) on the estimated value after the differential deformation filtering of the post-sedimentation casting strip to serve as a judgment principle of the final post-sedimentation casting strip closing time.
The real-time filtering method and the real-time filtering system simultaneously rely on theoretical data and actual measurement data of differential deformation between the main building and the skirt building to carry out real-time filtering operation, so that on one hand, the theoretical differential deformation can be corrected, and on the other hand, a theoretical basis can be provided for use of the actual measurement data in determination of the closing time.
The method can realize the accurate control of the settlement differential deformation between the main building and the skirt building of the super high-rise building, and can effectively predict the differential deformation which will occur in the future, so that the control of the closing time of the post-settlement casting belt is optimal.
The invention provides an effective solution for the technical problem of sealing the post-sedimentation casting belt; under the condition that the differential deformation meets the sealing requirement, the sealing time is determined accurately as soon as possible, and the method has important values in the aspects of improving the engineering efficiency, accelerating the engineering progress, reducing the engineering cost, reducing the construction difficulty and the like; the invention has simple calculation and high precision, and can ensure enough real-time performance even under the condition of automatic measurement.
