公路滑坡工程地质分析及防治方案

Highway Landslide Engineering Geology Analysis And Treatment Solutions

在建盘兴高速公路K5＋700-K5＋860段右侧,边坡开挖期间路堑顶外侧发生山体滑坡,前期滑坡速度较快,对深挖工点边坡及施工项目部存在极大的安全隐患,为确保边坡稳定,查明滑坡原因,对该处滑坡进行勘察布孔。最终得到滑坡岩土层物理参数,通过稳定性计算对滑坡体进行防治,结合实际情况,对比清除滑坡体和设置抗滑桩方案,确定选择设置抗滑桩方案,并对局部进行清除土方,同时对该处的深挖工点加强防护,以达到滑坡处理的目的,为以后类似滑坡工程提供指导和参考。

Highway under construction K5 ＋ 700 - K5 ＋ 700 section on the right side, the side slope cutting top lateral landslide during excavation, the early stage of the landslide speed faster, to dig worksite slope and the construction project department exists great potential safety hazard, in order to ensure slope stability, identify the cause of the landslide, the hole of landslide investigation cloth. Finally be landslide, rock and soil layer physical parameters through calculation of the stability of landslide prevention and control, compared to remove landslide and setting up the anti - slide pile project, combined with the actual sltuation, choose setting anti - slide pile scheme is determined, and the local clearing earthwork, the dig worksite to strengthen the protection of the place, in order to achieve the purpose of the landslide treatment, provide guidance and reference for future similar landslide engineering.
