| 摘 要： | 利用弹塑性有限元法分析成果 ,采用刚体极限平衡法分析土坡稳定 ,不仅考虑了土体应力 -应变非线性关系 ,同时能很方便计算土坡稳定的安全系数。避免了刚体极限平衡法单独计算时需要反复试算的过程 ,因而能够发挥有限元和刚体极限平衡法各自的优点

| Abstract: | An analysis on safety factor of slope was presented by using the result of finite elements. The nonlinear stress-strain relationship was considered,and the calculation of safety factor of slope became easy.Also repeating calculation based on general limit equilibrium method was avoided.So respective merit of them has been brought to play. |

| Keywords: | safety of slope finite elements general limit equilibrium method safety factor |
