考虑雨水入渗的边坡稳定分析方法

Method to Analyze Slope Stability in Consideration of Rain Infiltration

雨水入渗不仅改变了地下渗流场,也使边坡岩土体因浸泡而软化,抗剪强度变差,造成边坡失稳。为此,建立了一个考虑雨水入渗的地下水渗流模型,对雨水浸泡条件下土体强度变化的机理进行了探讨,并在此条件下对三峡某库区一边坡的稳定性进行了分析计算。

Rain infiltration changes the seepage field of ground water, softens the soil of the slope due to immersion and reduces the shear strength of the soil, resulting in unstability of the slope. A ground water seepage model in consideration of the rain infiltration is set up and the changing mechanism of the soil＇s shear strength under immersion of rain is discussed. Based on the above, the stability of a slope in Three Gorges reservoir is analyzed.
