摘　　要：以蒙屏高速公路K36+716~K36+875段滑坡为研究对象,通过现场勘查等方法确定滑坡的基本特征与成因机制,对滑坡稳定性进行定量评价,结果表明,滑坡为开挖和降雨引起的牵引式滑坡,在连续降雨工况下处于欠稳定状态。根据滑坡特征提出两种防治方案,经比选后建议采用圆形抗滑桩+方形抗滑桩+挡土板+三维网植草加固。Taking the landslide at K36+716〜K36+875 of the Mengping Expressway as the research object,the basic characteristics and formation mechanism of the landslide were determined through on-site surveys and other methods.Then the stability of the landslide was quantitatively evaluated.The results show that the landslide is a traction landslide caused by excavation and rainfall,and is in an unstable state under continuous rainfall conditions.According to the characteristics of the landslide,two control schemes are proposed.After comparison and selection,it is recommended to use round anti-slide piles+square anti-slide piles+retaining plate+three-dimensional net grass.
