| 摘 要： | 选取华北某市近5年管网破损记录中管材、管龄、管径、破损外因4个因素结合管网破损事件通过灰色关联评价方法进行分析,结果表明各影响因素对管网漏损的影响大小依次为:管材、管径、破损外因、管龄。经分析本地区管龄在10年左右,管径≤DN50的镀锌钢管和钢管更容易因管道腐蚀、配件质量、不均匀沉降问题而发生渗漏。

| Abstract: | The impact of leakage factor on water supply network was anlysised by gray correlation evaluation method,which the four factors was pipe material,pipe age,pipe diameter and external damage in the damage records of the pipe network of a city in north china in the past five years,as well as the damage events.The results showed the damage degrees from most significant to least significant are pipe material,pipe diameter,external damage,and pipe age.The result indicats that the pipe age of the area is about 10years,and the galvanized steel pipe and steel pipe with the diameter≤DN50are easily to leaking due to corrosion,fittings quality,and uneven settlement. |
