摘　　要：以北京周口店太平山西部滑坡为例,对滑坡体工程地质条件、滑坡体组构分析后认为,该滑坡在地质构造复杂的背景下,由人为开矿采空、大暴雨共同诱发形成。滑坡由两期极深层次的滑动作用完成,两者构成了套叠式构造组合形态。滑坡经历了褶皱变形阶段、蠕动变形阶段、滑动阶段、再次蠕变阶段、滑动破坏阶段、调整恢复阶段;并指出加大地质灾害知识的宣传力度,采取科学的防治措施是预防新的地质灾害发生的最佳途径。By a case study which analyzed the sliding mass engineering geological condition and structure of Taiping hill landslide, the author drew to a conclusion that the landslide was formed in a complex structure setting, due to mine exploiting and heavy rainfalls. The landslide was finished in two very deep - seated slip periods, their combinatorial modality is telescopic . The course of the landslide includes six steps： gestation in fold deformation, peristalsis, slippage, another squirm, devastating slippage, adjustive comback. So the best way to control hazards is propagandizing related knowledge and taking scientific precautions.
