Stability Analysis of Hazardous Rock in Wulipo Nature Reserue of Chongqing
[Purposes]Through the comprehensive evaluation results of the stability of hazardous rock,the influence of geological conditions on the stability of hazardous rock is analyzed.[Methods]Based on the Chongqing Wulipo Conservation Area Education Center project,this paper analyzes the basic charac-teristics of five hazardous rocks in the reserve through geological surveying,trough exploration,drilling and other survey results.Based on the analysis of the basic characteristics of 5 hazardous rocks in the re-serve,the stability of the rocks is qualitatively analyzed by geological analogy method and stereographic projection method,and then the stability of the rocks under different working conditions is quantitatively analyzed by limit equilibrium method.[Findings]The results show that all hazardous rocks are stable in their natural state,and are understable or unstable in heavy rain and earthquake conditions.[Conclu-sions]Since the inverse slope structure with hard upper and soft lower will reduce the stability of hazard-ous rocks,so it is necessary to monitor the cracks in the area where hazardous rocks are located.
