| 摘 要： | 文中以贵州省某填方路堤工程为依托,以地质资料和现场踏勘为基础,分析滑坡产生的原因和滑坡体稳定性,并提出滑坡治理比选方案。基于桩板墙抗滑利用率高、加固效果好且适用于散体结构的特点,最终确定采用桩板墙+混凝土刚性反压的加固治理方案。基于有限元强度折减法,采用ABAQUS对滑坡应力场和位移场进行数值分析,验证加固效果。

| Abstract: | Based on an embankment construction project in Guizhou Province,the causes of landslides and the stability of landslides is analyzed based on the geological data and on-site reconnaissance and then the landslide management comparison scheme is proposed.Based on the high anti-sliding utilization efficiency,good reinforcement effect and suitable for the bulk structure of the slab-pile wall,the reinforcement treatment plan of slab-pile wall with concrete rigid back is determined.Finally,based on the finite element strength reduction method,Abaqus is used to analyze the stress field and displacement field of the landslide,indicating that the reinforcement effect is good. |
