摘要
边坡稳定性评价,特别是对具有复杂几何特征的边坡,应作为三维问题来处理。作者将强度折减法应用于三维边坡稳定性分析中,通过三个典型的工程算例对几种常用的屈服准则进行比较,证明了在三维情况下采用莫尔-库仑等面积圆屈服准则代替莫尔-库仑准则是可行的。
The slope stability appraisal, especially to the slope with characteristic of complicated geometry, should be dealt with as the three-dimensional problem. In this paper, the strength reduction method is applied in the analysis on three-dimension slope stability, and a comparison of several yield criterions in common uses is presented through three typical examples. It is shown that using the Mohr-Coulomb equivalent area circle yield criterions to replace the Mohr-Coulomb yield criterions in three-dimenslonal is feasible.
