Study on Slope Stability & Stress-Deformation of Foundation Pit Based on FEA

Abstract:

In order to study the slope stress-deformation characters and stability of foundation pit after excavation, analyzed the examples based on the FEM theory, the results show :both the horizontal displacement of slope edge and settlement of slope top are small after support, and they are within the standard, deformation is not the reason for fissure: safety factor of slope is smaller than 1 after excavation, while the safety factor reaches require after support.
