某泥质粉砂岩类土质高边坡的滑坡治理研究

以某泥质粉砂岩类土质高边坡滑坡治理为例，分析了边坡的变形破坏特征和失稳破坏模式，并对滑坡稳定性进行计算。结果表明:全风化泥质粉砂岩类土质边坡失稳多发生在连续降雨期间，在雨水的作用下沿相对隔水层形成软弱滑动带。通过清方卸载、加固坡脚和坡面抗冲刷防护，能有效控制滑坡变形，确保工程运营安全。

Research on Landslide Control for a Soil-like High Slope in Argillaceous Siltstone

Taking the landslide control for a soil-like high slope in argillaceous siltstone as an example, the deformation and destruction characteristics and the failure mode of the slope were analyzed, and the stability was calculated. The result shows that, the failure of the soil-like slope in completely weathered argillaceous siltstone often arises in the period of continuous rainfall and, under the action of rain water, soft sliding zone comes into being along the relative confining bed. The protection measures, including unloading by earth cleanup and anti-scouring by consolidation of slope toe and surface, may control the landslide deformation and ensure the operation safety of the works.
