%X The application of composite geomembrane in water conservancy and hydropower engineering in China is mainly concentrated in fields such as channel,low dam,cofferdam,and dam seepage control,but rarely in high earth rockfill dam. With the application of composite geomembrane in the high earth rockfill dam of Luding hydropower station as a research background,we summarized some key points of  quality control for  composite geomembrane in terms of welding test,laying construction,quality control and welding quality inspection. We also proposed some specific construction techniques and detection methods for the suture of geotextile, welding of geomembrane, and the connection between geomembrane and concrete in  grouting gallery. This research provides reference for the application and quality control of composite geomembrane in similar engineering.
