摘　　要：管网水力模型的准确性是管网设计的基础。通常传统均匀配水模型认为模型管段内仅存在单一流向,这与实际情况不符,会造成管段水头损失计算误差。针对传统均匀配水模型中的单一流向和双向流管段的水力计算做了对比研究,论证了双向流计算方法的必要性,并推导出了给水管网管段水头损失计算的通式。The accuracy of water distribution system is fundamental to the design of pipe networks. The tradition- al uniform water distribution model usually believes that there is only one flow direction in a pipe line, which does not so agree with the factual situation that errors are made in calculation of pipe head losses. The paper makes a contrast between the one flow direction in traditional uniform water distribution model and the hydraulic calculation of the pipe model of two flow directions, demonstrating that the hydraulic calculation of the latter is necessary. And the general formula of the model is calculated in the paper.
