| Abstract: | In this paper,the model of optimization integration is used to optimize the forecasting results obtained by using the GM(1,1) model and the SVM-based model.This method is applied to the study of the building subsidence which is caused by foundation pit excavation of a high-rise building in Tianjin.The subsidence trend is forecast,and preferable simulation precision and forecasting reliability are obtained.The results are valuable for project construction,and this study also provides some reference for similar studies. |
