| 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: | In this paper, an analysis on safety factor of slope is presented by using the result of finite elements. It not
only considered the nonlinear stress-strain relationship, but also made the calculation of safety factor of slope easily.
Also repeated calculation based on general limit equilibrium method is avoided. Sorespective merit of them has been
brought to play. |

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