摘要
Abstract
A DMA partitioning method is proposed to address the complex composition and easy leakage of urban water supply pipelines.By understanding the concept of DMA and combining it with examples,determine the GIS system data of A city's water supply pipeline network,establish a pipeline network model,divide independent metering areas based on the hydraulic characteristics of pipeline segments and nodes,and test the DMA zoning effect of the model.The results indicate that the identification of the leakage occurrence area and leakage water vol-ume is accurate and rapid,meeting the requirements of nodes within the DMA partition.The partition scheme of this model reduces the leakage rate of the pipeline network by 12.99%,alleviates water resource waste caused by leakage,improves water resource utilization,achieves effi-cient location and effective repair of leakage parts,and provides technical guidance for the operation and management of complex urban water supply pipelines,with high application value.关键词
