摘　　要：目前边坡稳定性分析主要有工程地质分析法、刚体极限平衡法和数值模拟等,工程地质分析法和刚体极限平衡法是工程中使用最多和最成熟的方法,其中在我国常用传递系数法来求解滑坡稳定性,从工程应用中可以取得较为精确的结论,然而强度折减法所具有的独特优点使其逐渐在国内外受到关注,在边坡稳定分析中已逐渐得到认可。该文在传统极限平衡法的基础上,利用强度折减系数法对滑坡变形失稳过程进行了研究,得出了一些很有意义的结论。At present landslide stability analysis method mainly include engineering geological analysis method, rigid body limit equilibrium method, numerical simulation method etc. The engineering geological analysis method and rigid body limit equilibrium method are the most widely used and the most mature method in the engineering projects. The transfer coefficient method commonly used for landslide stability analysis in China can get accurate conclusion from the view of engineering application. But the unique advantage of the strength reduction method has gradually attracted the attention of the researchers around the world, and it has been gradually accepted in landslide stability analysis. On the basis of traditional limit equilibrium method, the paper studies the landslide deformation process of landslide with strength reduction method, thus gets some meaningful conclusions.
