摘要
陡峻边坡崩塌主要受控于岩体节理裂隙和结构面的组合,是西南地区频发的地质灾害之一。基于对李家屋脊崩塌区的工程地质条件的调查,阐述了崩塌危岩体的变形特征,进而对其成因机制和破坏模式进行了分析,对危岩体的稳定性进行了评价,对其治理给出了防治措施建议。
Collapse on the steep slope is one of the frequent geological hazards in southwest region,which is mostly controlled by the combination of joints and structural surfaces in rock mass. Based on the investigation of the engineering geological conditions of Lijiawuji collapse area, This article described the deformation characteristics of dangerous rock mass, and analyzed its formation mechanism and failure mode, then the stability of dangerous rock mass was evaluated, and finally the Treatment is given prevention measures as well.
