| 摘 要： | 在介绍有限元强度折减法基本原理的基础上，以某正实施加固的非均质边坡工程为研究对象，设置了两种最不利工况，采用有限元强度折减法，以等效塑性应变区贯通作为边坡破坏标准，分别对这两种工况下的边坡三维稳定性进行分析。计算结果表明:在微型桩的加固作用下，边坡的稳定系数大大提高，加固后的边坡是稳定的。

| Abstract: | Based on the introduction of the rationale of strength reduction finite element method, this paper took the works relating to an inhomogeneous slope under reinforcement as the study object and set two most adverse conditions ; then used strength reduction finite element method to carry out 3D stability analysis of the slope under the two conditions with the run-through equivalent plastic strain zone as the slope failure criterion. The result shows that the slope that is reinforced by miniature piles has a stability factor increased greatly, thus the reinforced slope is stable. |
