摘　　要：在矿山开发、水电建设过程中倾倒变形问题日渐突出。倾倒变形边坡一般具有反倾边坡结构,变形的过程和机理比较复杂、涉及的变形岩体范围较大、危害严重。论文以抚顺西露天矿边坡为例,通过岩体位移监测资料的跟踪分析、底面摩擦模拟试验,以岩体力学、松散介质力学原理为理论基础,探讨了采矿影响下边坡倾倒滑移体的变形机理,分析认为采矿引起的倾倒滑移变形问题是在特定的地质构造和采矿工程条件下产生的,并提出了岩体变形安全性分析方法。通过工程实例,验证了方法的实用性,并针对实际问题提出了变形整治对策。Toppling-sliding is a serious problem in mining and hydroelectricity construction. Taking Fushunxi Open Mine rock slope as an example, we analyzed displacement monitoring data of the rockmass and carried out base friction model tests. Based on rock mass mechanics and the theory of unconsolidated medium mechanics, the deformation mechanism of toppling-sliding mass due to mining is discussed in this paper. The main reason for the deformation of toppling-sliding mass is the combination of mining activity and geologic structure factors. The analytical method of stability of rookmass is proposed. An engineering case study is reported to show the practicability of this analytical method. The countermeasures are also proposed
