摘　　要：以盐源县的滑坡为背景建立了双排抗滑桩三维有限元模型,分析了在桩间距、滑面倾角、滑体材料、滑床材料、抗滑桩刚度等不同因素影响下,抗滑桩所承担的下滑力与该计算截面下总的下滑力之间的比例关系,得出了抗滑桩所承担下滑力与该计算截面下总的下滑力之间比例的变化规律。Based on the landslide of Yanyuan County, establish a three-dimensional finite element model of double-row anti-slide piles, analyze the sharing ratio between the sliding force bore by the piles and the total one of the calculation section under several various influential factors such as the pile distance, dip angle of slip plane, materials of sliding mass and sliding bed, and the stiffness of pile, etc. and obtain the variation law of sharing ratio thereof, which can provide reference for the design of double-row piles.
