Discussion on Evaluation Indices of Topology Structure for Urban Water Supply Pipelines Network
摘要
Abstract
[Objective]Pipeline distribution carries a large number of geographical environmental factors and rich knowledge of topology and graph theory.Due to the structural differences and transportation efficiency of water supply pipelines in different areas of a city,the topological structure analysis of urban water supply networks and the selection of evaluation indices have become particularly important.At present,a large number of network system researches focus on the analysis of topology structure,but there are relatively few researches on the topology of pipeline in water supply network system.In order to broaden the research field of water supply network and further improve the efficiency of future dispatching,[Methods]this study selected Shanghai,a typical city,as the research object based on the theory of graph theory and complex network research,and studies the pipe network topology of 11 water supply areas in Shanghai.The applicability of three topological indices of connectivity,ring formation rate and risk rate of single pipe in safety evaluation of water supply transmission and distribution system was discussed.space-L method was used to model and calculate the topological index scores of each water supply region,and the reasons for the differences among regions were proposed and evaluated according to the three indices.[Results]The result showed that the two indices of connectivity and ring formation rate show obvious spatial differences.On the whole,the connection degree and ring formation rate of Pudong Veolia were the highest among the divided regions,while Chongming was the lowest of the two indices.Fengjing Town of Jinshan District had the highest single pipe risk rate.[Conclusion]The study of topological indices in this paper is of great significance to the safety evaluation of water supply network,which can help to identify vulnerable links,evaluate emergency response ability,and improve the safety and reliability of water supply.In addition,this paper takes the lead in introducing indicators such as ring formation rate and single pipe risk rate in water supply network,and its evaluation method can provide reference for other cities.关键词
