摘　　要：勘查的基础上,分析成因。采用极射赤平投影法,对崩塌危岩体的稳定性进行评价。结果表明,有两处危岩体各有两组不稳定结构面,分别可能沿着190°和145°方向滑动,造成危岩体崩塌。建议采用拦石网工程进行防护。The causes were analyzed, based on the survey. The polar stereographic projection method was used to evaluate the stability of the unstable rock. The results show that two rock bodies, with two unstable structure surfaces each, may slide a long the direction of 190 ° and 145 °, resulting in dangerous rock collapses. Stone blocking was proposed for protection.

关 键 词：崩塌 稳定性 极射赤平投影
