摘　　要：基于极限平衡理论,运用边坡稳定分析软件ZSlope进行数值模拟,分析了土工格室垫层对边坡安全系数及临界滑动面的影响。结果表明:土工格室加筋层对边坡安全系数有比较明显的提高,加筋后边坡的滑动面向坡体内部移动,滑楔体尺寸变大。在此基础上,探讨了将土工格室加筋边坡等效为素土边坡进行计算的一种方法。Depending on limit equilibrium theory,numerical simulation was carried out with slope stability analysis software ZSlope to analyze the influence of geocell cushion on safety factor of slope and critical slip face.The result shows that the geocell reinforced layer may improve the safety factor of slope obviously,and the sliding plane of reinforced slope moves inward to the slope and the sliding wedge becomes greater in size.On this basis,a method allowing geocell reinforced slope to be equivalent to plain soil slope for calculation was discussed.
