摘　　要：双大路(双塘涧—柏峪)工程边坡位于北京市门头沟区,在边坡开挖过程中,坡面发生严重塌方并在坡顶出现了严重的变形裂缝,产生顺层滑移破坏,变形范围东西约220 m、南北约150 m,滑移面深度15～20 m。在查明边坡稳定控制性边界条件的基础上,通过多种数值模拟计算,分析了支护前后的稳定性,结果表明,治理后边坡达到了稳定状态,加固措施合理。Engineering slope of Shuangda road（Shuangtangjian to Baiyu） is located in Mentougou District of Beijing.During excavation process,the landslide on slope surface is serious and severe deformation cracks occurred on the top of the slope,causing bedding sliding failure,with deformation range about 220m from east to west,150m from north to south,with the depth of sliding surface about 15 to 20m.Based on identification of controlled boundary conditions of slope stability,through a variety of calculation methods of numerical simulation,the result shows that the reinforced slope is stable,so reinforcement measures are reasonable by analysising the stability before and after supporting.
