摘要
采用抗剪强度折减弹塑性有限元法分析含抗滑桩边坡稳定性优化问题,结果表明,在采用单排抗滑桩支护、坡脚和坡顶水平且坡体材料是各向同性材料时,桩布置在边坡中线上最有利于提高边坡稳定性,增大抗滑桩密度比增大桩径更能有效提高边坡的稳定性。
The strength reduction method was applied in elasto-plastic FEM to optimize the piles used to reinforce slope. The computated results showed that the piles placed in the middle of the slope could increase the stability of the slope most affectively, and the stability of the slope would be increased more quickly by reducing the longitudinal spacing than by increasing the radius of pile.
