摘　　要：通过对非线性映射理论及技术的研究和应用,提出了一种新的城市供水管网压力监测点布置方法。以某开发区供水管网为例,首先利用EPANET水力模拟软件对供水管网不同运行工况进行水力模拟,得到各节点压力模拟数值矩阵。然后,采用非线性映射分析方法对该压力模拟数值矩阵进行非线性映射变换,得到一系列独立的二维点群,实现压力变化特征相似节点的聚类和分组。最后,根据各节点压力变化的近似程度和特征,提出供水管网压力监测点的布置方案。应用表明,该方法实用性强,提高了节点压力分析的直观程度和可视化水平。A new arrangement method for pressure monitoring points in urban water supply network was proposed based on the nonlinear mapping theory and EPANET software. Taking a water supply network as an example, firstly, the EPANET software was used to simulate different operation conditions of the water supply network, and a simulated water pressure numerical matrix was obtained. Secondly, the simulated numerical matrix was mapped to two-dimensional plane by nonlinear mapping method, and the nodes were clustered and packed. Then, the arrangement method for pressure monitoring points was proposed according to the approximation degree of nodes＇ pressure changes. The case analysis shows that the method is practicable and the visualization of the water pressure study is improved.
