摘　　要：针对供水管网压力监测点在优化过程中,未充分考虑节点在整个供水管网系统中的影响性质,及监测点区域布局不合理导致管网运行信息监测效益低及重复布设的问题。为尽可能掌握整个供水管网的运行情况,提出采用影响修正指标及区分管网节点的压力反馈类型的压力监测点优化布置方法。即修正监测节点的理论有效检测范围,确保管网压力信息的精准表达,并以有效监测覆盖率和平均最大无量纲量为优化目标,利用NSGA-Ⅱ算法确定最终方案。将该方法用于某现实管网,并分析了不同的约束条件的参数值对模型的优化结果的影响,方案设计的结果显示监测点布置的效果良好,具有一定实际运用价值。In the process of optimizing the pressure monitoring points of the water supply network,the influence nature of nodes in the whole supply network system isn’t fully considered,and the unreasonable regional layout of the monitoring points leads to the low efficiency and repeated layout.In order to grasp the whole water supply network as much as possible,this paper puts forward a method by using the influence correction index and distinguishing the pressure feedback types.The theoretical effective detection range of monitoring nodes is modified to ensure the accurate expression,and the effective monitoring coverage rate and the average maximum dimensionless quantity are optimized,NSGA-Ⅱalgorithm is used to determine the final scheme.This method is applied to a real pipe network,and analyzed the influence of different constraint parameters on the optimization results.The results show that the effect of the monitoring point layout is well,and it has certain practical application value.
