摘　　要：以厦门淡溪斜坡为研究对象,采用Morgenstern-Price法和有限元法分别在天然、暴雨、地震3种工况下进行斜坡整体稳定性计算。2种方法对比发现,都在天然工况下斜坡稳定性较好,而在暴雨、地震工况下稳定性较差,但都不会发生整体失稳破坏;斜坡Ⅱ区比Ⅰ区发生局部破坏的可能性更大,且最易发生破坏的部位为坡脚临空条件较好的陡坎地形处。Taking the slope of Danxi village of Xiamen city as the research object,Morgenstern-Price method and finite element method were used to calculate the overall stability of slope under natural,rainstorm and earthquake conditions respectively.Through comparison,the two methods shows that the slope stability under natural conditions is better than that under heavy rain and earthquake conditions is worse,and the overall instability will not occur.The possibility of local failure in slope II region is greater than that in slope I region,and the most vulnerable part of failure is the steep terrain with good air condition at slope foot.
