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, the slope stability analysis mainly includes engineering geological analysis method, rigid body limit equilibrium method and numerical simulation. The engineering geological analysis method and rigid body limit equilibrium method are the most used and the most mature methods in engineering. Among them, the commonly used transfer coefficient method in our country However, the unique advantages of strength reduction method have attracted more and more attention both at home and abroad, and have been gradually recognized in slope stability analysis. Based on the traditional limit equilibrium method, this paper studies the process of landslide deformation and instability by using the method of strength reduction coefficient, and draws some meaningful conclusions.
