摘　　要：基于40处典型滑坡工程案例资料进行分析发现:滑坡的结构大多数为上软下硬结构,滑坡的水文地质结构大多数为滑坡体统一含水潜水型;大部分的上软下硬结构坡体对应的地下水水文地质结构多为滑坡体统一含水潜水型或滑坡体多层滞水(潜水)型。选择典型案例后岭滑坡,通过模型试验,从滑坡体变形的时间特性和空间特性方面分析滑坡的形成过程及特征,其呈现出牵引式滑坡及分块的破坏特征;水动力破坏模型为多层滞水(潜水)型。Based on the analysis of 40 typical landslide engineering cases,it is found that the structure of landslide is mostly soft on the top and hard on the bottom,and the hydrogeological structure of landslide is mostly unified waterbearing diving type of landslide body;most of the groundwater hydrogeological structures corresponding to the upper soft and lower hard structural slopes are of the unified water-bearing diving type or the multi-layer stagnant water(diving)type of landslide;the typical case,Houling landslide,is selected,and the formation process and characteristics of landslide are analyzed from the aspects of time and space characteristics of landslide deformation through model test.It presents the failure characteristics of traction landslide and block failure,and the hydrodynamic failure model is multi-layer stagnant water(diving)type.
