泉州双安高速公路高路堤边坡稳定性分析及治理设计

Stability Analysis and Remedy of High Embankment Slope of Quanzhou—Shuang'an Expressway

以已发生滑坡病害的高填路堤为研究对象,在不同地下水工况下,对治理前后的稳定性进行数值模拟分析。结果表明:该边坡的病害与地下水的影响关系密切,特别是地下水位的抬升,会对边坡的稳定造成很大的影响。在不利的工况下,采用抗滑桩加固后,边坡的稳定性模拟结果均达到规范要求,并且能够很好地遏制边坡的变形发展。

Taking the high-filled embankment which has occurred landslide disease as the research object,the numerical simulation analysis is conducted for the stability before and after the remedy under different underground water conditions. The results show that the disease of this slope is closely related to groundwater,especially the rise of groundwater level,which will cause large influence on the stability of the slope. Under unfavorable working conditions,the simulation results of the slope stability accords with relevant standards and slope deformation is restricted greatly after anti-slide pile reinforcement.
