摘要
通过对四川省小金县魏家山危岩体采取工程地质测绘、槽探、工程测量、取样测试等工作手段,查明其地形地貌、地层岩性、地质构造、水文地质与工程地质条件等,并对其形成机制和破坏模式进行分析。岩体结构、结构面组合特征、地形地貌、卸荷作用等因素是危岩体形成的主控因素,危岩体失稳有滑移式、倾倒式和坠落式三种破坏模式。
Through working means of engineering geological mapping, trenching, engineering survey and sampling test, the author identifies its topography and geomorphology, statum lithology, geological structure, hydrogeology and engineering geology, analyzes formation mechanism and failure mode. Rock structure, the combination of structural surface features, topography and unloading effect are the main controlling factors of formation of unstable rock mass.
