碾压混凝土大坝渗漏分析与处理

Analysis and Treatment of Leakage of Roller Compacted Concrete Dam

本课题透过碾压混凝土大坝漏渗表面现象,通过分析碾压混凝土坝体施工工艺控制中存在的问题和坝体结构特点,找到坝体产生渗漏的源头,并结合坝体接(触)缝、碾压混凝土与防渗层之间的渗水特点,有的放矢的提出了采用水泥灌浆为主的堵漏方式,解决了碾压混凝土坝体渗漏的难题,并节约了工程成本,为碾压混凝土大坝渗漏处理提出了可供借鉴的方案。

In this topic,through the leakage surface phenomenon of roller compacted concrete dam,by analyzing the problems existing in the construction process control of the roller compacted concrete dam body and the structure characteristics of the dam body,the source of the dam body leakage is found,and a plugging method based on cement grouting is proposed by combining the seepage characteristics between the dam body contact seam,roller compacted concrete and anti-seepage layer,which solves the problem of roller compacted concrete dam leakage and saves engineering costs.This paper proposes a plan for the leakage treatment of roller compacted concrete dam.
