摘　　要：滑动结构面的抗剪强度在岩体滑坡的稳定性计算中是最重要的参数,也是最难以确定的。基于岩体抗剪强度是多种因素影响下的随机变量这一认识前提下,本文以西柏坡“中共中央解放军总部”旧址滑坡为例提出了确定岩体斜坡滑动面抗剪强度的动态反分析方法,并对该方法获得的抗剪强度的实用性进行了分析。结果表明,反分析方法是获得岩体斜坡滑动面抗剪强度的最经济、合理的途径。In the analysis of stability of rock mass slope, the resistance to shearing of slipping plane of rock mass slope, one of the most important parameters, is very difficult to determine. The resistance to shearing of rock mass is the stochastic variable controlled by many factors, so the authors put forwards a dynamic analysis method for determining the resistance to shearing of slipping plane of rock mass slope, and analyzed the practicability of the method. The result showed that the dynamic analysis method is effective in practice to determining the resistance to shearing of slipping plane of rock mass slope.
