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.
