Foundation Pit Deformation during the Excavation and Simulation

Abstract:

Based on the background of foundation pit excavation of a village, the process of excavation is simulated by FLAC^3D .And the calculation and analysis is combined with the engineering practice. The results show that the deformation of foundation pit is mainly composed of ground surface settlement, and the maximum deformation occurred in the middle of the pit wall at the top of the part. The surface subsidence with the ongoing of the excavation, the general surface subsidence trend is rising. When it comes to the foundation pit, when the settlement velocity is very large, the foundation turns to be unstable, which need supporting methods. Flac³^D program applied on the excavation of rock and soil deformation law study is feasible. The result of the study to further relevant basis are provided for the practical engineering and have certain practical application value to the rock and soil deformation in the process of excavation research.
