| 摘 要： | 为促进危岩体的防治和"5.12"地震后的重建工作,以青川麻柳沟危岩体为例,从地质结构、地形地貌和变形特征三方面探讨危岩体的形成机制.然后通过定性的野外调查和定量的极限平衡法分析危岩体稳定性.结果表明.麻柳沟危岩体形成于压致蠕变一拉裂作用,以倾倒式破坏为主,三个危岩体中,一个欠稳定,另两个稳定.

| Abstract: | To promote the prevention and treatment of dangerous rock-masses and the reconstruction after the May 12-th Earthquake,their formation mechanism is explored.As a case,the dangerous rock-masses in Maliu Gully,Qingchuan,are studied in terms of topography,geological structure and deformation characteristics.And their stability is analyzed,based on the qualitative field investigations and the quantitative limit-equilibrium studies.The results show that the masses resulted from pressure-induced creep-crack with the dumping type in the main and only one unstable of the three. |
