Abstract The finite element limit equilibrium method (FELEM) is increasingly used in slope stability analyses. The greatest advantage of the FELEM is its time-saving analysis process, which does not require the iterative strength reduction process used in the strength reduction finite element method. The conventional FELEM calculates stresses using the finite element method with the elastic-perfectly plastic Mohr-Coulomb model and searches for the critical slip surface with the minimum safety factor. To further enhance and broaden the applicability of the FELEM, a 2D and 3D slope stability FELEM using elastic finite element stress fields is proposed. Five typical soil slope problems, a 2D rock slope problem involving a nonlinear failure model and a 3D shallow slope problem are adopted to validate the proposed FELEM. The results indicate that this method can be applied to solve various slope problems.

使用弹性有限元应力场进行边坡稳定性分析

摘要 有限元极限平衡法（FELEM）越来越多地用于边坡稳定性分析。FELEM 的最大优点是其省时的分析过程，它不需要强度折减有限元方法中使用的迭代强度折减过程。传统的 FELEM 使用有限元方法和完全弹塑性 Mohr-Coulomb 模型计算应力，并搜索具有最小安全系数的临界滑动面。为了进一步增强和拓宽 FELEM 的适用性，提出了使用弹性有限元应力场的 2D 和 3D 边坡稳定性 FELEM。五个典型的土壤边坡问题，一个涉及非线性破坏模型的 2D 岩石边坡问题和一个 3D 浅边坡问题被采用来验证所提出的 FELEM。
