摘要
随着城市规模快速发展,供水管网安全问题日益突出,亟需对供水管线牢固性进行评估。以北方某大中型城市局部区域为例,采用模糊数学综合评价法,建立基于管材属性、人口密度、交通属性和建筑物属性等因素的供水管网安全性评价体系,评定安全性评价等级。研究结果表明:15.03%的管线属于"优秀"等级,84.08%的管线属于"良好"等级,另外有0.89%的管线属于"中等"等级,需对其加强安全监测。供水管网安全性评价体系研究成果对城市供水管线安全性的预测具有重要参考价值。
With the rapid development of urban scale,the safety of water supply distribution network is increasingly prominent,so it is urgent to study and evaluate the solidity of water supply distribution pipelines.Taking part of a large and medium-sized city in the north for example,safety evaluation system of water supply distribution network was established,based on pipe property,population density,traffic property and building property,by fuzzy mathematics comprehensive evaluation method,and safety assessment grade was evaluated.The safety grade percentages of pipelines belonging to excellent,good and medium were 15.03%、84.08%and 0.89%respectively,and monitoring needed to be strengthened.The safety evaluation system of water supply distribution network has important reference significance for safety prediction of urban water supply distribution network.
