Abstract降雨入渗模型与边坡稳定性方法有机结合是研究降雨诱发滑坡稳定性的有效方法。在深入分析降雨入渗基本理论的基础上,将Mein-Larson入渗模型与基于饱和土、非饱和土以及近似非饱和土的无限边坡稳定性分析方法有机结合,综合考虑了高强度短历时和低强度长历时两种降雨情形,拓展并改进了基于Green-Ampt入渗模型的饱和土和近似非饱和土无限边坡稳定性模型,并依托典型边坡实例对各评价模型的计算结果和适用性等进行了对比分析。
Other Abstract

The combination of rainfall infiltration models and slope stability methods is an effective way to study types of landslides. Based on thorough analysis on the basic theory of rainfall infiltration,Mein-Larson modified model is combined with infinite slope stability models of saturated soil,unsaturated soil and approximate unsaturated soil. According to two rainfall cases of short duration rainfall with high intensity and long duration rainfall with low intensity,the infinite slope stability model of saturated soil and approximate unsaturated soil based on Green-Ampt infiltration mode is extended and modified. Finally,the calculation results and applications of the models are analyzed and compared by a typical slope case.
