阳江核电水库堆石坝防渗灌浆施工技术研究

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。本文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

Study on technology of curtain grouting for seepage prevention of rockfill dam in Yangjiang nuclear power station reservoir

The leakage of rockfill dam in the Yangjiang reservoir is serious, affecting the safety and normal operation of the dam. Taking the engineering practice into consideration and making the comparison on economy and technology, grouting for seepage prevention was adopted to repair the original seepage control system. In this paper, the grouting technology of this project was studied, grouting field tests were done respectively in the rockfill area and transition area, and the practical and reasonable grouting schemes were put forward.
