摘　　要：山区降水时空分布不均匀,工程性缺水问题突出,须修建水源项目,以满足山区供水需要。山区水源项目地形地势复杂,输水管道线路较长,在施工过程中受不可控因素影响造成的调整和变更较多,输水管道工程设计和施工相对复杂。文章从输水管道的管材、管径、水力学计算、结构、横断面、阀门及附属建筑物设计等方面出发,分析了输水管道工程的设计要点,旨在为山区水源项目输水管道工程设计提供参考。Thes patial and temporal distribution of precipitation in mountainous areas is uneven,and the problem of engineering water shortage is prominent.It is necessary to build water source projects to meet the needs of water supply in mountainous areas.The terrain of the mountainous water source project is complex,and the water transmission pipeline route is long.In the construction process,there are many adjustments and changes caused by uncontrollable factors,and the design and construction of the water transmission pipeline engineering are relatively complex.This paper analyzes the key design points of water transmission pipeline engineering from the aspects of pipe material,pipe diameter,hydraulic calculation,structure,cross section,valve and ancillary building design,aiming to provide reference for water transmission pipeline engineering design of water source projects in mountainous areas.
