云阳县滨江大道路基挡土墙变形分析与加固

Analysis on Retaining Wall Deformation in Binjiang Road of Yunyang County and Reinforcement

摘要:

云阳县滨江大道路基挡土墙在运营工况下，由于路基运营环境的变化导致了填土的物理力学性质的改变，挡土墙发生了位移和变形。在分析了变形原因的基础上，提出了抗滑桩预应力锚索联合加固方案，并取得了良好的治理效果。介绍了该工程加固方案设计及抗滑桩预应力锚索施工工艺。

Abstract:

Due to the changes of subgrade in the operating environment, the changes of physical and mechanical properties of the fill were caused, displacement and deformation happened in the retaining wall. On the basis of analysis on deformation, joint reinforcement of pre-stressed anchor cable and anti-sliding pile was proposed with good effect. The paper introduced the design of reinforcement scheme and the construction technology of pre-stressed anchor cable for anti-sliding pile.
