摘要
滑坡的稳定性受降雨、地震等因素影响较大,在各种稳定性分析方法下的安全系数有一定的差别.以芦山地震震区某土质滑坡为例,通过现场的工程地质勘查,分析了该滑坡的基本特征.在Geo-Studio的Slop/W模块中建立模型,分析该滑坡在天然、暴雨、地震3种工况下的稳定性,采用摩根斯坦—普瑞斯法、毕肖普法、简布法与一般方法计算安全系数.
The stability of landslide is greatly influenced by such factors as rainfall and earthquake.The safety coefficients of various stability analysis methods have some differences. We take one soil landslide in certain quake zone as an example,and analyze the basic characteristics of this landslide by engineering geological exploration. This paper establishes the model by Slop / W module of Geo-Studio,and analyzes the stability of the landslide under three trigger conditions（ natural,rainstorm and earthquake） respectively. The safety coefficients are calculated by four kinds of evaluation modelsMorgenstern-Price,Bishop,Janbu and Ordinary.
