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.
某混凝土重力壩在高水頭運行工況下,箇彆地質條件複雜壩段存在跼部較大滲漏.通過壩體穩定性複覈,研究製訂減小壩基滲漏量及增加壩基抗滲破壞能力的帷幕補彊灌漿技術方案及質量控製方法,併通過試驗驗證帷幕補彊灌漿施工參數及工藝.通過實施帷幕補彊灌漿,減輕瞭壩基滲漏水抽排壓力,增彊瞭防滲能力,提高瞭壩基穩定性,促進大壩長期安全穩定運行.

Under high water pressure, large leakage was found at some sections with complex geo-logical 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 construc-tion parameters and process were verified by experiment. Good effect was obtained after treatment.
