摘　　要：在川中危岩体的几何形态、地层岩状、地质构造特征、水文地质特征的基础上,根据力学特征建立了危岩的拉裂式倾倒崩塌计算模型。用Sarma法在天然状态和饱水状态下进行稳定性计算分析,找出了危岩崩塌的主要原因,并建议采取加固与排水措施,对减少危害有较大的工程实际意义。On the basis of Chuanzhong dangerous rock of geometry, stratified rock condition, structural and hydro geologic features, according to mechanical properties , founding calculation pattern of dangeraus rock of capsizing collapsing . The paper uses the Sarma method to evaluation and stability analysis of dangerous rock on nature and well-watered condition, analyzing mainly causes, some measures to reinforce and drain off water are proposed . It is of great significance to reduce harm in engineering practice.
