摘　　要：重庆市万州区上海大道末端滑坡近期由于后缘修建路堤而回填加载,发生变形破坏,对前缘居民的生命和财产安全构成了严重威胁,准确判断该滑坡的稳定性,并采取相应的防治措施显得尤为重要。因此,对该滑坡的成因进行了分析,并对其在天然和暴雨两种工况下的稳定性进行了评价,得出:滑坡在天然状态下处于基本稳定状态,在暴雨条件下处于不稳定状态,地质灾害危险性大。对此,提出了回填反压、完善截排水系统、裂缝回填等防治措施。The landslide at the end of Shanghai Ave. , Wanzhou Dist. , Chongqing was subject to deformation fracture recently, which was caused by embankment construction in the back with backfill load and endangered life and property of the residents in the front. Then it was most important to judge the landslide＇s stability accurately and take corresponding control measures. This paper analyzed the landslide genesis and evaluated the stability thereof under natural and rainstorm conditions, then concluded that the landslide is in stable state basically under natural condition and in unstable state under rainstorm condition, thus risks geological hazard. As a result, the control measures, such as back pressure backfilling, drainage interceoting system improving and crack backfilling, were proposed.
