This paper analyzed the slope stability by means of the finite difference software and using strength reduction theory,respectively gained the safety coefficient of slope and the stress strain diagram under damage.And made sensitivity analysis through the formation of formal test on slope stability parameter,so as to draw the influence of different parameters to slope stability safety coefficient,provided some reference for parameters analysis value of this problem.%借助有限差分软件利用强度折减原理对边坡稳定性进行分析,分别得出边坡的安全系数和破坏时的应力应变图,并通过构造正交试验对影响边坡稳定的参数进行敏感性分析,以得出不同参数取值对边坡稳定安全系数的影响,为此类问题分析时参数的取值提供一定的参考。
