中文摘要：

从力平衡的角度,分析了抗滑桩的抗滑阻力与滑体的下滑力之间的依存关系以及传递过程.利用弹性力学理论,推导出桩后土体应力场的分布函数.通过绘制应力等值线图,发现抗滑桩与土体之间产生土拱现象的机制是滑体内的应力状态由不平衡逐渐到达平衡的结果,属于应力拱的表现形式.

英文摘要：

Anti-slide pile is a major landslide prevention measure.This paper analyzes the transition process of force between soil and anti-slide pile based on force equilibrium.According to the relationship of acting force and reacting force between soil and anti-shde pile,the stress distribution in the soil behind anti-slide pile is obtained.From the stress isograms,it is shown that the mechanism of soil arc between anti-slide pile and soil is the result of the stress state from imbalance to balance in soil.
