摘　　要：目的为了解决供水水量不足时管网的水力计算问题.方法考虑节点流量随节点水压的动态变化,提出一种新的管网水力计算方法.结果用管网算例验证了方法的正确性和使用性.结论新方法有效地解决了供水水量不足时,管网节点配水量未知情况下的水力计算问题,在计算得到节点水压和管段流量的同时,确定了节点实际配水量.The shortages of water resources are common in causing many cities' water demand over its supply, while traditional calculation methods for network are unsatisfactory in results. This paper puts forward a new method of theoretical calculation pondering the random changes of nodal flow being determined by pressure, which can obtain solutions with nodal flow and pressure, and computational example is induced showing the correctness and applicability of the method. The method resolves the problem of hydraulic calculation with unknown nodal flow.
