摘要

干海子滑坡位于大渡河流域

规模巨大。为研究该滑坡的稳定性

在对滑坡基本特征及变形破坏特征等深入研究的基础上

采用极限平衡法（Geo-slope软件）和有限差分法（FLAC-3D软件）对该滑坡的稳定性和应力应变特征进行了计算、模拟。稳定性计算模拟主要从深层、浅层及局部稳定三方面入手分析

计算模拟结果与滑坡的宏观地质现象均具有较高的吻合度。通过对该滑坡定性与定量的稳定性分析

判断其浅层滑体在暴雨工况下将处于极限平衡状态

而深层滑体在地震工况下依旧处于基本稳定状态

所得结论为下一步滑坡防治工作提供了翔实的依据。

Abstract

Ganhaizi landslide is located in Dadu River Basin

which has large scale volume.In order to study the stability of the landslide

on the basis of researching the basic characteristics

deformation and failure of the landslide

its stability and stress-strain features were then calculated and analyzed by limit equilibrium method and finite difference method

which mainly analyze landslide′s deformation features from the respect of the deep layer

shallow layer and local stability. The results of the analysis are in line with the macro-geological phenomena.Through qualitatively and quantitatively analytic judgements

it is shown that the shallow sliding body in the storm conditions will be in the state of limit equilibrium

and deep sliding body in seismic condition will still be in the basic steady state.The result obtained will provide a reliable basis for the future landslide prevention work.
