摘要
将Mohr-Coulomb等面积圆屈服准则和有限元强度折减系数法相结合,提出了在平面应变条件下有限元分析模型的选取、边界条件的处理方法、收敛条件,以及采用大型通用有限元程序ANSYS分析边坡稳定时c、φ值的替换原则,最后用于分析某工程深基坑复合边坡的稳定问题,给出该工程边坡的安全系数。
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 undex plane strain condition, disposal of boundary conditions and convergence condition were prodded 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.
