摘　　要：对植生袋复垦边坡技术进行了详细介绍,采用极限平衡理论中的瑞典条分法、简化Bishop法对降雨入渗条件下的边坡稳定性问题进行了模拟分析。研究结果显示:在降雨入渗影响下,抗滑稳定性系数最低为1.848,明显高于规范规定的1.3,说明植生袋复垦边坡显著降低了边坡滑动趋势,边坡稳定性得到显著提高。The slope technical parameters using vegetation bag reclamation are introduced in detail, and the simulation analysis on stability under rainfall infiltration is studied by Sweden slice method and simplified Bishop method with the limit equilibrium theory. The research showed that the minimum coefficient of sliding stability under rainfall infiltration is 1. 848, which is significantly higher than the codes 1.3 stipulated in. Slopes with vegetation bag reclamation significantly reduced the slope sliding trend, and its stability was remarkably increased.
