摘　　要：东山村滑坡面发育于新近系全风化碎屑岩与下伏褐煤层或砂、泥岩基底之间。滑坡后缘滑移清晰,变形活动强,中部拉张裂已形成错台陡坎。定量工况及载荷组合计算认为滑坡体极易失稳产生滑动,对居民生命财产有极大影响,有必要进行彻底处治。The Dongshancun slide is developed between Neogene full weathering clastic rock and the underlying lignite bed or sandstone - claystone base. The slide of back margin is clear. The deformation is intense. The middle tension fissure has formed the displacement steep stairs. According to the quantitative working and loading composite calculation, the slide body is very easy of instability and slide down, which will very seriously influence the life and property of resident and must be thoroughly settled.
