摘　　要：就长距离输水管道的材质、管道口径和衬里等管道特性因素,结合各设计规范的推荐公式进行了对比分析,并根据各水力计算公式的适用范围及限制条件,指出不同管道特性条件可能对水力计算结果造成的影响,建议在大口径长距离输水管道设计中采用对三个紊流区域均适用的柯列勃洛克公式替代海澄威廉公式,以期得到较为安全合理的设计成果。The formulae of hydraulic calculation recommended by the design code were compared for long distance water supply pipelines with substantive condition of different size, pipemaking and lining materials, and the suitability and limitation of each formula are discussed. The potential effect of pipe feature on hydraulic calculation has been indicated and it was recommended that the Colebrook equation, which is suitable in tri-turbulent zones could be best to replace the Hazen-Williams formula to get better result of rational design with higher safety.
