摘要
滑坡作为一种地质灾害,由于其作用因素及运动机理的多变性和复杂性,一直是世界各国研究的重要地质和工程问题之一。降雨是诱发边坡滑坡的主要原因之一。本文以饱和-非饱和渗流数学模型为基础,运用GEO-SLOPE计算软件模拟了不同的降雨强度和降雨持时对边坡稳定性的影响,并探讨各参数变化对边坡稳定性安全系数的影响,为降雨条件下的边坡稳定性分析提供了可靠的依据。
Landslide,as a major geological disaster,is always one of the important geological and engineering problems in the world because of its variability and complexity of role factors and moving mechanism.Rainfall is one of the main reasons which evoke landslide.The paper used Geo-slope calculation software to simulate impact of different rainfall intensity and lasting on the slope stability and discuss the impact of parameter change on safety factor of slope stability.It can provide a reliable theoretical basis for the analysis of slope stability under the condition of rainfall.
