摘要
重庆黔江汽车东站滑坡是前缘人工开完及后期降雨综合作用下发生滑移变形的典型。通过滑坡特征、形成机制及影响因素敏感性系数分析:坡脚开挖为滑坡滑动提供了临空条件;降雨等地下水渗透是滑坡变形破坏的激发因素;影响因素φ的敏感性系数明显大于C的敏感性系数。在此基础上对滑坡采取抗滑桩支护及地表截、排水措施综合治理措施。
The landslide of Qianjiang east bus Chongqing station is a typical example which is being induced by people excavation at first and rainfall after that.Through the analysis to landslide characteristics,formation mechanism and influencing factors,the foot landslide excavation will provide air condition for slope sliding.The rainfall and groundwater seepage are main motivating factors of slope deformation and failure.The sensibility coefficient φ is obviously bigger than C.On this basis,the measures of anti-slide pile supporting,surface intercepting and drainage,and comprehensive treatment have been adopted to deal with the landslide.
