摘要
从管网实际出发，在管道测试的基础上，提出用几种常用水头损失公式确定管径ｄ、海曾－威廉斯公式系数Ｃ和柯尔勃洛克公式中ｋ值及用管道相对负荷指数分析管道工况的方法．并结合实例进行了计算和验证．该方法同时考虑了管径及阻力系数对管网计算的影响，使工况分析更接近实际，可解决工程上长期未解决的难题．
On the basis of analyaing pipe-networks and pipe test,a methodmethod of determination of d, C and k values by using the usual loss-of-head formula is prestented. Analysis of pipe working state by means ofpipe relative indexes and checking computations are also given in thispaper. This method takes the variations of both pipe diameter and piperesistence coefficient into consideration,which makes working state analysismore practical. Many difficult problems in engineering may be solved bythis method.
