摘　　要：为了保持边坡稳定而采用布置抗滑桩的方式,在边坡加固措施中较为普遍并且效果非常显著,但现有的抗滑桩加固边坡的措施在设计上仍然存在诸多不足以及不合理之处。本文主要采用数值模拟的方法并以强度折减法原理为理论基础,对天然边坡的稳定性、单排桩加固边坡稳定性和双排桩加固边坡进行了稳定性分析。通过研究布桩位置、排距、桩径、桩长及间距与边坡的安全系数的关系,对比了采用不同加固方案对同一边坡的加固效果,总结了抗滑桩加固边坡的优化设计路线,为以后抗滑桩加固边坡的工程提供参考。In order to maintain the stability of the slope,the arrangement of anti slide piles is more common and effective in the slope reinforcement measures,but there are still many deficiencies and irrationalities in the design of the existing anti slide pile reinforcement measures.In this paper,the stability of natural slope,single row pile reinforced slope and double row pile reinforced slope are analyzed by using the method of numerical simulation and the principle of strength reduction method.By studying the pile location,row spacing and pile diameter,and the relationship between the pile length and spacing and the safety factor of the slope,the reinforcement effects of different reinforcement schemes on the same slope are compared,and the optimal design route of the slope reinforced by anti slide piles is summarized,which provides a reference for the slope reinforced by anti slide piles in the future.
