摘　　要：为研究抗滑桩位置对边坡稳定性的影响,选用有限元软件ABAQUS进行数值模拟分析,运用强度折减法计算不同状态下的边坡安全系数,通过对比安全系数的大小来判定抗滑桩位置对坡体稳定性的影响程度。研究发现,抗滑桩能有效提高边坡的安全系数,且安全系数的大小与抗滑桩的位置关系密切。数据显示,坡顶附近安全系数较高,距坡底1/3坡宽处的安全系数相对较小。Impact of anti-slide pile slope was studied by making numerical simulation and analysis using the finite element software ABAQUS,calculating the safety factor for slope under different conditions with the strength reduction method and determining impact of the position of anti-slide pile on slope stability by comparing the size of safety factor.The study showed that the anti-slide pile could effectively increase the safety factor for slope and the size of safety factor was closely related with the position of anti-slide pile.The data indicated that the safety factor was large in vicinity of the slope top and small at a width of 1/3on the slope base.
