摘　　要：本文以万山地质文化产业园基岩边坡为例,采用赤平极射投影法、Sarma法相结合,定量计算和评价了边坡的稳定性,得出了完全一致的计算和评价结论:该高陡岩质边坡目前处于不稳定状态。文中采用两种方法计算并相互印证,对下一阶段该边坡的设计、施工等提供了重要依据,对类似工程有很好的参考和借鉴作用。In this paper,taking the bedrock slope of Wanshan Geological and Cultural Industrial Park as an example,the stability of the slope is calculated and evaluated quantitatively by the combination of stereographic projection method and Sarma method,it is concluded that the high and steep rock slope is in an unstable state.Two methods are used to calculate and confirm each other,which provides an important basis for the design and construction of the slope in the next stage,and has a good reference for similar projects.
