阳江核电水库堆石坝防渗灌浆施工技术研究

Research on Technology of Curtain Grouting for Seepage Prevention of Rockfill Dams in Yangjiang Nuclear Power Station Reservoir

阳江核电水库堆石坝防渗体系的渗漏情况严重,影响了坝体的安全和正常使用,结合工程实际,通过经济技术对比,采用防渗灌浆的形式对原有防渗体系进行修复。对该工程的灌浆施工技术进行了试验研究,分别对堆石区和过渡区进行了现场灌浆试验,提出了切实可行的灌浆方案。

The leakage of rockfill dams in the Yangjiang Reservoir is seriously affecting the safety and normal operation of the dam. grouting for seepage prevention is adopted to repair the original seepage control system by taking the engineering practice into consid- eration and making a comparison between economy and technology,. In this paper, the grouting technology of the project is studied, grouting field tests are done respectively in the rockfill area and transition area, and practical and reasonable grouting schemes are put forward.
