Abstract
In order to promote prevention of dangerous rock mass and reconstruction after the Wenchuan Earthquake, the formation mechanism of dangerous rock in Xiao Jiawan is studied in terms of geological structure, topographical landform and deformation characteristics. On this basis, the stability of the dangerous rock mass are qualitatively and quantitatively evaluated by means of stereographic projection and limit equilibrium method. The results of the study show that the dangerous rock mass is instable and needs to be treated. In connection with each specific characteristic of dangerous rock mass, comprehensive control measures which integrate aritificial clearing, mortar bolt, mortar crack filling, concave supporting, volley-unstable rock retaining wall and SNS passive safety net are put forward, and the effect of the measures is good.关键词
