摘要
滑坡对人类活动危害最普遍的地质灾害类型,三峡库区为我国滑坡灾害最为典型地区。本研究通过计算万家坝滑坡体剖面工况载荷组合,对三峡库区万州万家坝滑坡变形区进行稳定性复核研究,为三峡库区滑坡治理提供典型案例。结果显示:万家坝水文地质条件简单,地下水对砼微腐蚀性;滑坡体为一大型沿基岩面滑动的中层横长式滑体,建议采用抗滑桩或桩墙结合方式进行变形区治理;需避免雨季施工。
The Three Gorges Reservoir area is a typical landslide hazard area in China.This study carries out the stability recheck study of the Wanjiaba landslide deformation zone in the Three Gorges Reservoir area in order to provide a typical example for landslide control in the Three Gorges Reservoir area.The results indicate that hydrogeological condition in the Wanjiaba area is simple with micro-corrosiveness of groundwater to concrete.The sliding mass of the Wanjiaba landslide is a large,intermediate,transverse,long sliding body sliding along the bedrock surface.It is suggested that anti-slide pile or pile wall should be combined in order to control the deformation zone and construction must be avoided during the rainy season.
