摘　　要：在复杂地质环境条件下的管道建设中,崩塌是常见的地质灾害之一,从危岩体潜在失稳方式的角度对管道建设中常见的危岩体进行了分类,对各类危岩体用DDA数值模型分析方法研究失稳方式的形成机制,用静力解析计算方法构建力学模型,对各类危岩体在无外力、地震、暴雨等工况下的稳定性评价方法进行了介绍,为管道线路的选定、施工建设和运行维护提供依据。Collapse is one of common geological hazards in pipeline construction under complex geological conditions.Classified are common dangerous rock masses in pipeline construction according to its potential instability pattern,DDA numerical model analysis method is applied to research the formation mechanism of instability pattern of different dangerous rock masses,static analytic calculation method is applied to establish mechanics model.Introduced are stability evaluation methods of different dangerous rock masses in working conditions with no external force,earthquake and rainstorm,which provides basis for selection of pipeline route,construction and operation and maintenance of pipeline.
