摘　　要：瓜州县二水源水源地设计近期供水规模为2.2万m^(3)/d,位于瓜州县昌马洪积扇东北缘;新建配水厂设计近期供水规模为2.0万m^(3)/d,位于安西总干渠北侧。水源地位置高,距城区远,为充分利用地势高差,节约能源,采用长距离重力流输水管道。本工程特别对管道水锤防护等安全措施进行了系统的分析及设计,提高输水安全性,为长距离输水工程提供参考。The second water source project,which is located in the notheast margin of Changma alluvial fan in Guazhou County,has the capacity of 22,000 m^(3)/d.Newly-built water distribution plant is designed to supply 20,000 m^(3)/d water in the near future,which is located in the north of Anxi main canal.In order to make full use of terrain dfference and save energy,long-distance gravity flow pipeline is adopted.In this project,pipeline water hammer protection and other safety measures are analyzed and designed sys-tematically.Safety of water conveyance is improved.It provides a reference for long-distance water conveyance project.
