某收费站管理场区边坡滑坡原因分析及处治设计

Cause Analysis and Treatment Design of Landslide in Management Area of a Toll Station

结合工程的自然地质条件、水文地质条件和人类工程活动等,分析了某高速公路收费站管理场区在边坡开挖时诱发滑坡的变形特征和形成机理,通过稳定性计算分析,最终采用调整场区位置+反压回填+抗滑桩的综合处治方案对滑坡进行处治,该滑坡目前已处于稳定状态,达到了处治目的,取得了较好的工程处治效果。

This paper combined the natural geological conditions,hydrogeological conditions and human engineering activities of projects,the deformation characteristics and formation mechanism of the landslide induced by slope excavation in the management area of a highway toll station were analyzed.By the calculation and analysis of the stability,the integrated treatment scheme of adjusting site position combined with back pressure,backfill and anti-slide pile was finally adopted to treat the landslide.At present,the target landslide is in a stable state and has achieved a good treatment effect.
