| 摘 要： | 在边坡稳定问题的研究中引入了接触单元的概念，基于局部破坏理论，提出了一种新的边坡稳定系数的计算方法。同时与传统方法进行了对比分析，实例计算结果比较准确，结果表明该计算方法是可行的和准确的。从而进一步证明了局部破坏理论的正确性和边坡软弱结构面是控制边坡稳定的关键因素。

| Abstract: | Contact element is combined with slope stability problem and a new calculation method of slope safety factor is put forward based on partial failure theory. The computation result obtained by flew method is very closed to that of the traditional method, which illustrates that the new method is feasible and correct. Therefore, it is further proved that local failure theory is correct and weak structural plane will control the stability of slope. |

| Keywords: | contact element slope stability weak structural plane strength reduction method of interface parameters partial failure theory |
