摘　　要：某新建高速公路K149+600~K149+700段左侧路堑边坡开挖后失稳,发生整体滑移,影响运营安全。最初设计采用卸载+挡墙支挡,未能有效阻止边坡滑移,在极端暴雨条件下,滑坡持续下滑导致挡墙开裂。文章基于现场地质勘察资料,对滑坡机理进行分析总结,并对滑坡稳定性进行计算,根据计算结果制定滑坡处治方案。The left cutting slope of the K149+600~K149+700 section of a newly-established expressway is unstable after excavation,and the overall slippage occurs,which affects the operation safety.The unloading+retaining wall support is used in the initial design,which fails to effectively prevent the slope from slipping,and under the extreme rainstorm condition,the landslide continues to slide and causes the retaining wall to crack.Based on the on-site geological survey data,the landslide mechanism is analyzed and summarized,and the stability of the landslide is calculated.The landslide treatment scheme is formulated according to the calculation result.
