采用HyperMesh程序建立h型抗滑桩加固边坡的三维有限元数值模型,即综合考虑h型抗滑桩桩-土、梁-土及桩-梁的共同作用,并基于有限元强度折减法,通过ABAQUS有限元软件对三维模型进行数值模拟,同时引入参数q来判别h型抗滑桩的加固效果。根据此参数,并考虑安全系数、桩身最大滑坡水平推力,对h型抗滑桩夹角θ、桩间距、桩排距等设计参数进行优化分析。结果表明,达到较好加固效果时的最优夹角为15°,最优桩间距为5倍桩宽,最优桩排距为5倍桩宽。
By using HyperMesh program, a three-dimensional finite element numerical model of h-type anti-slide piles strengthened slope is established. The combined effect of h-type anti-slide piles- The ABAQUS finite element software is used to simulate the three-dimensional model and the parameter q is introduced to determine the reinforcement effect of the h-type anti-slide pile. According to this parameter and taking into account the safety factor and the horizontal thrust of the maximum landslide of the pile body, the design parameters such as the angle θ of the h-type anti-slide pile, the spacing between piles and the distance between piles are optimized. The results show that the best included angle is 15 °, the best piles spacing is 5 times piles width and the best piles distance is 5 times piles width.
