Horizontal Displacement Prediction Research of Deep Foundation Pit Based on the Least Square Support Vector Machine

Using of the least square support vector machine to predict the horizontal displacement of deep foundation pit. According to the measured time series data of horizontal displacement of foundation pit, using the least square support vector machine (SVM) to set up the relation model of foundation pit horizontal displacement and time, taking the actual excavation monitoring data as learning and training samples and testing samples, the calculated results and the actual monitoring results were compared and analyzed. The results show that using the least squares support vector machine (SVM) to predict the horizontal displacement of foundation pit, which was with higher prediction accuracy, the method with prediction error is small, fast calculation, less data, etc., precision can satisfy the need of engineering. The method Confirmed that is an effective method to solve the problem of the foundation pit deformation prediction.
