摘　　要：阳江核电平堤水库大坝是广东省首座采用沥青砼心墙堆石坝,工程建成下闸蓄水后出现严重渗漏现象。对大坝进行防渗灌浆处理后,渗漏量和防渗墙渗透系数均能满足设计和规范要求,灌浆达到了预期效果。但灌浆处理后,47.00 m高程以上沥青砼心墙依然存在渗漏缺口,且有进一步扩张的趋势,应引起足够重视。The dam of pingdi reservoir in yangjiang nuclear power plant is the first rockfill dam with asphalt concrete core wall in guangdong province.After the construction of the project,serious leakage occurs after the sluice is stored.After the anti-seepage grouting treatment of the dam,both the leakage amount and the permeability coefficient of the anti-seepage wall can meet the design and specification requirements,and the grouting has achieved the expected effect.However,after grouting treatment,there is still leakage gap in asphalt concrete core wall above 47.00m elevation,and there is a trend of further expansion,which should be paid enough attention to.
