摘要

在大型滑坡治理工程中常常采用双排抗滑桩，锚索双排桩和刚架双排桩是常见的两种型式。采用有限元程序ANSYS分别建立锚索双排桩和刚架双排桩的有限元分析模型，对比分析这两种型式双排桩的内力分布，找出能更好发挥抗滑效果的结构型式。通过对比分析可知，锚索双排桩的前后两排桩的内力分布差距十分明显，刚架双排桩的前后两排桩的内力分布差距较小，所以，刚架双排桩能够更好地发挥抗滑效果。选取锚索双排桩和刚架双排桩2个工程实例，监测分析发现锚索双排桩的前排桩侧向位移和弯矩均远小于后排桩，刚架双排桩前后两排桩的位移和弯矩比较接近，这与有限元分析结果相吻合，因此，双排抗滑桩的设计中建议采用刚架双排桩

Abstract

Double-row piles are often used to the large-scale landslide. The anchor double-row piles and the frame double-row piles are the two common types. Based on the finite element program ANSYS

finite element models of the two types double-row piles are established separately. Compared the internal force distribution of anchor double-row piles with frame double-row piles

it is found that the frame double-row piles could be better able to play anti-slide effect. For the anchor double-row piles

the difference of internal force distribution between the front and back row piles is very obvious. For the frame double-row piles

the difference is very small. Taking two engineering cases

an anchor double-row piles and a frame double-row piles for examples

through monitoring and analyzing the stresses and displacements of the piles

it is shown that the results are consistent with the finite element analysis. So we suggest using the frame double-row piles in the design
