Abstract: Gaolingtou I dam is a double-curvature concrete arch dam. After operation with low temperature and high water level,seepage increased.In the end of 2008, cement grouting and chemical grouting was carried out which decreased the seepage, good effect was gotten.

摘要: 高岭头一级水电站大坝为混凝土双曲拱坝,在经历了连续低温高水位的不利工况后,渗漏量大增致使廊道被淹。大坝在渗流异常且未进行处理的情况下运行了10 余年, 高水位情况的最大渗漏量达394.75 m3/ d。2008 年冬至2009 年春采用水泥灌浆和化学灌浆对坝基进行了处理,处理后渗漏量最大不超过1 m3/ d,效果十分显著。
