摘要： 某混凝土重力坝在高水头运行工况下，个别地质条件复杂坝段存在局部较大渗漏。通过坝体稳定性复核，研究制订减小坝基渗漏量及增加坝基抗渗破坏能力的帷幕补强灌浆技术方案及质量控制方法，并通过试验验证帷幕补强灌浆施工参数及工艺。通过实施帷幕补强灌浆，减轻了坝基渗漏水抽排压力，增强了防渗能力，提高了坝基稳定性，促进大坝长期安全稳定运行。
关键词: 帷幕灌浆, 补强加固, 应用
Abstract: Under high water pressure, large leakage was found at some sections with complex geological conditions in a concrete gravity dam. Based on stability calculation, curtain grouting scheme and its quality control method were put forward for reinforcement. In addition, the construction parameters and process were verified by experiment. Good effect was obtained after treatment.
Key words: curtain grouting technology, reinforcement, application
