阿尔及利亚南部某市供水工程设计

Design of Water Supply Project for a City in Southern Algeria

阿尔及利亚南部城市某供水工程输水管道横跨撒哈拉沙漠737 km,经过路线地形复杂。管道流态包含重力流和压力流,同时具有长距离、大流量、高扬程的特点。本文介绍了该供水工程中的管道设计,对输水管线进行了正常状态和过渡状态水力计算,有效地保证了供水系统的安全性及可靠性。

Water delivery pipeline of a city＇s water supply project in southern Algeria spans the Sahara Desert about 737km,the terrain of route is complicated.Pipeline flow state includes gravity flow and pressure flow;meanwhile,it has the characteristics of long distance,large flow and high lift.The paper introduces pipeline design of the water supply project,and hydraulic calculation in normal state/transient state will be carried out for water delivery pipeline,which can efficiently ensure safety and reliability of water supply system.
