摘要：
An intelligent inversion system based on support vector machine (SVM) was established, and creep tests of soft soil were conducted in laboratory under the background of a large foundation pit project of Taihu tunnel. An innovative analysis method was proposed by combining the intelligent inversion and creep tests. The basic physical and mechanical parameters and creep parameters of relevant soil layers were determined combined with the monitoring data. The feasibility of the method in long-term stability analysis and deformation prediction of soft soil foundation pit under overloading was verified by analyzing the deformation at the site of soft soil foundation pit under overloading. The method was applied to the optimization design under overloading of Taihu tunnel, and good results were obtained. Copyright ©2022 Journal of Zhejiang University (Engineering Science).
