膨胀土边坡多排小方桩和圆桩抗滑效果的对比分析

摘要

Numerical simulation analysis on the anti-sliding mechanism of preliminary support system of multi row piles based on strength reduction method in the design of expansive soil slope.The design and optimization of multi row small diameter round piles are analyzed.The results show that the treatment effect of using multi row piles is better than that of the round pile,which has some theoretical reference value for the design of the expansive soil slope.%对膨胀土边坡设计的预支护多排小方桩支护体系的抗滑机理采用强度折减有限元法进行了数值模拟分析,并设计多排小直径圆桩方案进行了对比优化研究分析.结果表明,小型方桩抗滑措施的抗滑效果比圆桩的好,对膨胀土边坡的整治措施设计具有一定的理论参考价值.
