Abstract: In order to solve the problem of water supply in the Lhasa New District,it is necessary to set up a large riverside groundwater field in the Lhasa River.According to the regional hydrogeological conditions and the location of the proposed water source,hydrogeological survey,hydrogeological drilling,single hole and group hole pumping tests and other related tests work were carried out,and the hydrogeological parameters of the water source were obtained.According to the obtained parameters,the scheme of the water supply was arranged in a plane and space,and the water intake structures was designed.In the process of survey and design,the spatial layout of water intake structures,the problems in design and construction,and the protection of water source areas were analyzed and discussed,which provided some practical experiences for the construction of large water source areas in the Lhasa River Basin.
