Abstract: The long-distance high-head water delivery project is an important way to solve the uneven distribution of water resources. In order to ensure the safety and economy of the operation of the water delivery project, the design and construction of the long-distance high-head water delivery project must be combined with the specifi c local conditions, and the optimal water delivery line, water delivery method, and pipeline design and design must be selected. Construction plan. Based on this, this paper analyzes the design method of longdistance high-head water delivery project for reference.
