软弱夹层岩质顺向边坡变形机理及防治对策研究——以贵阳高新收费站边坡为例

Deformation mechanism of weak interlayer rock slope and its prevention and control: a case study on the slope of Guiyang Gaoxin Toll Station

以贵阳高新收费站边坡工程为研究对象,对边坡的地形地貌、构造、岩性、水文地质、风化作用等因素进行详细的研究,综合分析边坡工程地质条件,对变形机理进行深入剖析,在此基础上采用数值模拟。结果表明:边坡处于蠕滑-拉裂-滑移型滑坡的初始阶段;防治重点是控制边坡的变形,监测结果表明,达到边坡治理的目的。

Taking the slope engineering project of Guiyang Gaoxin Toll Station as the research object,we studied the topography,structure,lithology,hydrogeology and weathering of the slope,and analyzed the deformation mechanism of the slope.Then we carried out numerical simulation.The results showed that the slope was in the initial stage of creep-pull-crack-slip landslide.The key point of prevention and control was to control the deformation of the slope.The monitoring results showed that the goal of slope control was achieved.
