持续降雨下某非饱和土质滑坡稳定性分析

大量的事实表明,降雨是影响边坡稳定性,导致边坡失稳的最主要和最普遍的环境因素。对夹江县某土质浅层滑坡在降雨条件下稳定性进行了分析评价,通过有限元分析的方法,建立数值模型,分析在不同降雨条件下,稳定性随时间的变化规律。结果显示该滑坡在降雨条件下稳定性随时间逐渐降低,处于不稳定状态,应采取相应的加固措施确保安全。

Analysis on Stability of Unsaturated Soil Landslide under Continuous Rainfall

A large number of facts show that rainfall is the main and most general environmental factor influencing slope stability and leading to slope failure.This paper evaluated the stability of a soil shallow landslide under rainfall in Jiajiang County in such manner that,through building numerical model by FEM,the law of stability changing with time on different conditions of rainfall,was analyzed.The result shows that this landslide,on condition of rainfall,would have the stability reduced with time gradually,and is so instable that it should be reinforced to ensure the safety.
