为深入研究坡顶超载环境下抗滑桩加固边坡的整体稳定性，依据现行地基规范并结合地基承载力理论，取均布超载强度 q 计算抗滑桩-边坡体系的安全系数和桩身内力分布。在此基础上，讨论坡顶超载外边缘线至坡顶不同水平距离 Lq 对加固后边坡稳定性的影响，将边坡顶部均布超载视为埋深为零的条形基础，考察不同超载强度和超载作用位置条件下边坡的整体稳定性及桩间土拱效应。研究表明：抗滑桩-边坡体系在特定的桩间距范围内形成土拱，坡顶不同超载强度和超载作用位置影响着桩间土拱的分布、发展及破坏规律，土拱效应集中反映了抗滑桩的作用机制和加固效果。

The local surcharge is usually regarded as the bar foundation on ground surface .To investigate the influence of the local surcharge on the stability and failure mechanism of slope-pile system ,a series of uniformly distributed surcharge q is illustrated to numerically solve the safety factors of stabilized slopes and the internal forces along reinforcing piles combined with the formula of the subsoil bearing capacity in foundation code .Moreover ,the different horizontal distance Lq (from the outside edge line of uniformly distributed surcharge to the top of slope ) under a given local surcharge is uti-lized to discuss this problem in detail .In particular ,the intensity and position of the uniformly distributed surcharge on the top of slope are also taken to study the slope stability and the soil arching effect between adjacent piles .The results show that when the anti-slide piles are inserted in a potential sliding slope subjected to a local surcharge ,the soil arching will occur in a certain pile spacing .The intensity and position of locally uniform surcharge will influence the distribution , process and failure mechanism of soil arching as well as the working performance of anti-slide piles to a certain extent .
