摘　　要：白鹤滩水电站右岸尾水系统灌浆工程,工程量大、项目多、工作面分散、施工强度高,区域内地质构造复杂,有较大的断层及错动带,施工技术难度大。通过对白鹤滩水电站地下洞室群内复杂地质构造部位固结灌浆的施工技术研究,总结出一套行之有效的灌浆方法、施工工艺及相关措施,以保证灌浆质量能够满足相关要求,整体灌浆效果明显。The grouting works of tailrace system on the right bank of Baihetan Hydropower Station are characterized by large quantity, large number of projects, scattered working surfaces, high construction intensity and complicated geological structure in the area. There are also large faults and staggered zones, which make construction technology difficult. Through the research on the construction technology of consolidation grouting for complex geological structure parts in the underground cavern group of Baihetan Hydropower Station, a set of effective grouting methods, construction techniques and relevant measures are summarized to ensure the grouting quality can meet the relevant requirements and the overall grouting effect is obvious.
