摘　　要：以老鹰岩崩塌危岩体为研究对象,采用地质分析法对崩塌的形成机制进行研究.通过现场地质勘探和地质参数确定,利用理正岩土赤平极射投影与数值计算分析典型危岩体的稳定性,对天然条件、暴雨条件和地震作用等三种工况进行分析.研究结果表明:老鹰岩崩塌危岩体在天然条件下处于基本稳定状态;但在暴雨、地震等外界条件作用时,处于欠稳定状态.Taking the hawk rock collapsed dangerous rock as the research object, the geological analysis method was used to study the mechanism of the collapse formation. Through on-site geological exploration and determination of geological parameters, the stability of typical rock of the dangerous rock mass was analyzed by using the polar projection and numerical calculation of the rock and soil. The three conditions of natural conditions, storm conditions and seismic effects were analyzed. The results of the study indicate that the hawk rock collapsed dangerous rock is basically stable under natural conditions; however, under the influence of external conditions such as heavy rain and earthquakes, they are in a state of under-settling.
