首先对滑坡区工程地质及水文地质条件进行阐述,着重介绍了滑坡的空间、结构形态及变形特征,并从地形地貌、岩土体类型、地下水条件等方面分析了深格滑坡的形成机制。同时利用极限平衡法对滑坡在各种工况下的稳定性进行了分析,对各参数的敏感性进行研究,通过反算法确定合理的滑带参数,计算了滑坡的剩余下滑推力,提出了治理的建议措施。
First of all, the engineering geology and hydrogeological condition of the landslide area are expatiated. The space, structure and deformation characteristics of the landslide are introduced emphatically. The forming mechanism of the deep-seated landslide is analyzed from topography, geotechnical type and groundwater conditions. At the same time, the stability of the landslide under various working conditions is analyzed by using the limit equilibrium method. The sensitivity of each parameter is studied. The reasonable parameters of the landslide are determined by the back-analysis method, and the remaining gliding thrust of the landslide is calculated. Recommended measures.
