| Abstract: | This paper analyzed the stability problem of some deep foundation pit by using Mohr-Coulomb equivalent area circle yield criterion and strength reduction by FEM.The selection of FEM model under plane strain condition,disposal of boundary conditions and convergence condition were provided by this paper.In this paper,the transformation method of the values of C and φ was also given for analyzing stability problem with the large common software-ANSYS.Finally,the safety factor of the slope was obtained. |
