| 摘 要： | 对比分析了土质边坡稳定性计算中条分法和有限元法的特点，讨论了在有限元法中边坡稳定系数的计算方法，并针对铜钟水电站库区左岸滑坡分别采用条分法和有限元法研究其稳定性，计算结果表明两种计算方法得到的滑坡稳定系数规律相同，但条分法计算值一般大于有限元值，反映出条分法中部分基本假设与实际情况存在一定差异。

| Abstract: | In this paper , the characteristics of slice method (SM) and finite element method (FEM) for earth slope stability calculation are contrasted and analyzed , and calculation method for slope stability factor in FEM is discussed . The slope stability for left bank landslide of Tongzhong reservoir is analyzed by means of SM and FEM respectively . The calculation indicates that the variation of slope stability factor is the same from two methods , but calculation values from SM are greater than those from FEM , which suggests the principle presupposition of SM is different from practices. |
