Application of SVM Time Series Prediction Model in Foundation Pit Excavation Engineering
Predict the surrounding surface settlement and vertical displacement of the support structure caused by excavation of the foundation pit,this paper relies on the foundation pit project of a subway station in Qingdao to preprocess the on-site monitoring data.The SVM time se-ries prediction model is used to predict the surface settlement of the deep foundation pit and the vertical displacement of the pile top.The pre-diction results are processed and analyzed,and the prediction accuracy of the model is measured by RMSE,MAE,MBE and R2.The results indicate that the SVM model has certain potential in predicting the deformation of deep foundation pits,but further improvement and optimiza-tion are still needed.
