摘　　要：提出了一个基于压力驱动建立管网漏损模型的方法,首先利用EPANET中EMITTER(扩散器)特性建立压力驱动水力模型,然后在模拟结果上建立管网漏损模型。通过具体算例阐述了建立符合实际的管网漏损模型的过程。结果表明,对于部分节点需水量不能全部满足的管网,压力驱动分析方法比需水量驱动分析方法得到的水力模型更符合实际,并且在压力驱动水力模型基础上建立的管网漏损模型更准确。The method of network leakage model establishment was put forward based on pressuredriven analysis. At first,the pressure-driven hydraulic model was established by EMITTER（ diffuser）characteristics in EPANET,and then the network leakage model was set up based on simulation results.According to the specific case,the process of network leakage model establishment was elaborated. The results indicated that the hydraulic model obtained by pressure-driven analytical method was closer to the practical situation compared with water demand driven analytical method as the water demand of any nodes could not be satisfied. Meanwhile,the network leakage model was more accurate based on pressure-driven hydraulic model.
