大关门水库土坝除险加固中搅拌桩水泥土截渗墙的设计应用

Design and application of cut-off wall made of the mixed round cement-soil in the reinforcement to earth dam of Da-guanmen reservoir

大关门水库在对土坝进行除险加固设计中采用了多头小直径搅拌桩水泥截渗墙方案,经计算分析比较,该方案经济合理,技术可靠,防渗效果好,对土坝的渗流稳定和抗滑稳定都起到了较好的作用。

During the design of reinforcement to earth dam of Da-guanmen reservoir,we take the plan of cut-off wall made of the mixed round cement-soil with multi-head and small diameter.Through the computation and comparison,this plan features economic feasibility,technical reliability,good result of seepage,and good effect to seepage stability and stability against sliding of the earth dam.
