摘　　要：供水管网对于城市极其重要,为了能对其进行智能化管理,供水管网模型已经在越来越多的城市管网中得到运用。供水管网模型需要定期进行校核,监测点布置方案的好坏对于供水管网的模型校核来说相当重要。城市供水管网规模庞大,水力状况复杂,且模型中存在数量很多的节点,如何得到合理的监测点布置方案是一个值得研究的问题。本文以H市供水管网为案例,对布置的备选节点进行筛选,然后基于相似度运用遗传算法进行监测点优化布置。对布置结果的验证表明,本文提出的监测点布置方法,具有较好的效果,能有效提高水力模型校核的精度,可为现状城市供水管网新监测点布置提供决策参考。Water distribution networks are extremely important for cities and in order to manage them intelligently,network models have been used in more and more.The water distribution network model needs to be calibrated periodically,and the placement of sensors is very important for the model calibration.The scale of urban water supply network is huge,the hydraulic condition is complicated,and there are huge numbers of nodes in the model,so how to get a reasonable sensor placement is a important problem.In this paper,city H's water distribution network was used as a case study,removed bad nodes in thealternate nodes,and then use genetic algorithm to optimize the placement of sensors based on the node similarity.The verification of the placement results shows that the purposed method has a good effect,can effectively improve the accuracy of the hydraulic model calibration and can provide a decision reference for the new sensor placement in the urban water distribution network.
