合理设置抗滑桩桩问距对确保滑坡稳定具有重要作用。针对土拱理论在抗滑工程中的应用，对抗滑桩工程中土拱效应的影响因素进行了较为详细的介绍，讨论了各影响因素对抗滑桩临界桩间距的影响，并以工程实例说明了各种算法的差异，对于抗滑桩工程的设计和施工具有一定的指导意义。%The reasonable anti-slide pile's spacing setting would play an important role in economy to ensure slope stability. According to the applicatian of soil arch theory in anti-slide projects, the influencing factors for soil arching effect in anti-slide pile engineerings are introduced in detail, and the effects of the influence factors on the critical spacing between anti-slide piles are also discussed. Then, the differences of various calculation algorithms are illustrated by practical projects, which could provide a gniding significance for the design and construction in anti-slide Bile engineerings.
