Applied Research of Finite Element Model in Deformation Analysis of Subway Station Foundation Pit Excavation
The deformation of foundation pit excavation of subway station will cause hidden trouble of construction safety.Exploring and studying the deformation law of foundation pit excavation of subway station can effectively reduce the construction risk and ensure the safety of foundation pit.Based on the case of Xintiandi park station of Metro line 1 in Changzhou,this paper simulates the foundation pit excavation of the station on the settlement of soil surrounding the foundation pit,the settlement of layered soil layer,deep horizontal displacement and settlement of diaphragm wall with modified Mohr-Coulomb model by finite element analysis.And through the comparison and analysis with the measured data,the model analysis method is proved to be scientific and reasonable and has guiding significance for the similar subway foundation pit excavation.
