摘　　要：为解决传统微观水力模型节点流量为定值,难以模拟管网减压降漏、管网优化调度等压力变化以及节点流量需随之变化的弊端,结合我国华南地区中小型城镇管网实例,建立压力驱动管网水力模型,并应用于管网压力控制漏失。结果表明:在传统微观水力模型基础上将漏失量加到各节点上作为节点流量组成部分,形成压力驱动水力模型,并采用传统微观水力模型校核与压力驱动模型校核相互反复循环校核方式进行模型校正,可使其更加贴近真实管网运行情况。针对不同应用需求,构建不同精度水力模型,在传统微观水力模型基础上进行不同改进,提高模型精准度及应用效果。In order to solve the disadvantages of the traditional micro-hydraulic model, namely node flow rate being a fixed value, difficult simulation of pressure variations in network pressure reduction and leakage control, network optimization scheduling and node flow rate needing to be changed, com- bined with the network examples in small and medium-sized towns in southern China, the pressure-driven hydraulic model was built and applied to the leakage control of network pressure. The results showed that the leakage rate was added into each node as the node flow component based on the traditional micro-by- draulic model to form the pressure-driven hydraulic model, and the model was checked by the traditional micro-hydraulic model and the pressure-driven hydraulic model repeatedly, which could make it more close to the operation of real network. According to different application requirements, hydraulic models with different precisions were built and modified based on the traditional micro-hydraulic hydraulic model to improve model accuracy and application effect.
