STABILITY ANALYSIS OF TWO-STEP SLOP REINFORCED WITH SOIL NAIL BASED ON FEM STRENGTH REDUCTION METHOD

基于有限元强度折减法分析二级边坡土钉墙加固对边坡稳定性的影响。根据强度折减法的基本原理分析土钉加固条件下二级边坡的稳定性问题,通过设定不同的土钉直径及长度,分析边坡整体稳定系数的变化规律。研究过程中,重点分析土钉直径及土钉长度对边坡总体稳定性的影响规律。研究结果表明,土钉长度对边坡的稳定性的影响较大,土钉直径影响不明显。研究结果对实际工程中的二级边坡稳定性分析有参考价值。

The influence of two step slope reinforced with soil nail on the stability of the slope was analyzed based on the finite element strength reduction method.According to the basic principle of strength reduction method,soil nail reinforcement two step slope stability problem was analyzed with different diameter and length of the soil nailing.The influence of soil nailing diameter and soil nail length on the stability of two step slope were analyzed in this paper.The results show that the soil nail length has great influence on the stability of the slope,but the influence of soil nail diameter is not obvious.The results have reference value for the stability analysis of two step slope in actual engineering.
