不同抗滑桩在复合多层滑床条件下的受力分析

Stress Analysis of Different Anti-slide Piles under the Condition of Composite Multi-layer Sliding Bed

为了防止复合多层滑床边坡的滑动造成地质灾害,此文对不同抗滑桩在复合多层滑床条件下的支护承载性能进行分析,结果表明:单排抗滑桩加固边坡时,随着离桩底高度的增加,抗滑桩的水平位移越大,桩身的最大位移在桩顶;双排桩对边坡的加固中,离桩底的距离越远,抗滑桩受到滑坡的推力越大,前排桩和后排桩的水平位移随之增大,后排桩的水平位移较前排桩的位移大。研究结果为类似复合多层滑坡治理工程提供参考。

In order to prevent geological disasters caused by the sliding of composite multi-layer sliding bed slope,the supporting performance of different anti-slide piles under the condition of composite multi-layer sliding bed is analyzed.The results show that the horizontal displacement of the anti-slide pile increases with the increase of the height from the pile bottom.The maximum displacement of the pile body is at the top of the pile.In the reinforcement of slope by double-row piles,the greater the distance from the pile bottom,the greater the thrust of the anti-slide pile,the greater the horizontal displacement of the front row pile and the back row pile.The research results provide reference for similar composite multi-layer landslide treatment.
