摘　　要：四川省南江县近年来由于降雨等因素,频频发生滑坡等地质灾害,给人民带来了巨大损失。降雨诱发土质滑坡有其自身的特点和发生机制。一般来说降雨诱发的土质滑坡沿基覆界面滑动,为浅表层滑坡。以南江县王正傍滑坡为土质滑坡典型研究对象,对其工程地质条件和变形破坏特征进行研究,论述了王正傍滑坡的成因机理,利用geo-studio数值模拟软件对其稳定性进行对比计算。研究成果可为滑坡的预警和治理提供参考。Due to factors such as rainfall, landslides and other geological disasters occur frequently in Nanjiang County of Sichuan Province in recent years, huge losses happen to the people. Soil landslide induced by rainfall has its own characteristics and mechanism. Generally speaking, the soil landslide along the base of the rainfall induced landslide is sliding along the base cover interface. In this paper, Nanjiang County Wangzhengbang landslide as the typical research object of soil, the engineering geological conditions and deformation characteristics were studied, the paper discussed the formation mechanism of Wangzhengbang landslide, the simulation calculation software on its stability by using Geo - Studio numerical. The research results can provide reference for the early warning and control of landslide.
