摘要
运用有限元分析软件ABAQUS,建立设置防滑铲的公路斜坡软弱土路堤模型,探讨有无防滑铲时圆弧滑动面的移动情况;采用强度折减有限单元法,对比分析有无防滑铲时路堤模型的稳定性,研究不同软弱层厚度条件下防滑铲对斜坡路堤稳定安全系数的影响,并提出相应的组合优化措施。
A slope emban km ent model with anti-slide shovel was established using the finite element software Abaqus.The movement of circular slip surfaces with or without anti-slide shovel was discussed.The stability of embankment model with or without anti-slide shovel was analyzed by strength reduction elastic-plastic finite element method.The influence of anti-slide shovel on stability under different thickness of weak layer was obtained,and the corresponding combinational optimization measures were put forward.
