摘　　要：介绍不同胶水比条件下掺减水剂对固结灌浆浆液粘度的影响试验。试验结果表明掺减水剂对于胶水比1∶0.6、1∶0.5的浆液粘度影响尤为明显,可显著提高浆液的可灌性,在溪洛渡水电站坝基固结灌浆施工工序中掺加聚羧酸减水剂,固结灌浆施工质量有效提高,取得了较好的技术经济效益。The paper introduces the test of effect of water reducing agent on slurry viscosity of consolidation grouting un- der different water- cement ratios. The test results reveal that water reducing agent has significant effect on viscosity of slurry with mix proportion of 1：0.6 and 1：0.5 in particular, which can remarkably improve plaeeability of slurry, thus providing technical support for the dam foundation consolidation grouting of Xiluodu hydropower project.
