摘　　要：水利工程施工中经常会出现渗漏情况,基础防渗处理可有效避免这种情况,防止渗流速度过快,使水利工程更加安全。帷幕灌浆是防渗最基础、最有效的方式。以某水库水利工程为例,分析了帷幕灌浆施工技术要点,对帷幕灌浆质量与效果进行评价,检测结果表明ω≤5 Lu,符合吸水率要求,ω<1 Lu的段数、ω=3~5 Lu的段数和ω=1~3 Lu的段数分别占13%、32%和54%,说明可以在水利工程中广泛推广该技术,以提升建设质量。Seepage often occurs in the construction of water conservancy projects.The foundation anti-seepage treatment can effectively avoid this situation,prevent the seepage speed too fast,and make the water conservancy project safer.Curtain grouting is the most basic and effective way to prevent seepage.Through taking a reservoir water conservancy project as an example,the study analyzes the key technical points of curtain grouting construction,and evaluates the quality and effect of curtain grouting.The test results show thatω≤5 Lu meets the water absorption requirements,and the number of sectionsω<1 Lu,ω=3~5 Lu andω=1~3 Lu account for 13%,32%and 54%,respectively,indicating that this technology can be widely promoted in water conservancy projects to improve construction quality.
