摘　　要：通过及时把握相关市政给水管道爆管事件报道,了解我国各地大型爆管事故现状和爆管发生的原因及其规律性。就爆管原因、月份、时间、空间、管材、管径、管龄等的分析,发现本年度内施工、老化、土层变动、气温变动等是爆管事故的主要原因;1、7、8、12月容易发生爆管事故;一日内,上午5-11时容易发生爆管事故;道路交叉口附近较容易发生爆管事故;发生爆管的管材多为铸铁管和水泥管;管径多在DN300-500范围和DN1200左右;发生爆管的铸铁管管龄一般在20-30年之间,而水泥管一般在15年左右。Current pipe burst state and the reasons and regularity of urban water supply systems all over the country can be learned preliminarily by analysis on the water pipe burst news of municipal water supply system in 2010. Analysis on the reason, time, space, materials, pipe diameters, pipe age points that： construction, aging, foundation changes, temperature changes, exclusive load, overpressure, engineering quality are the main reasons for pipe burst of this year; January, June, July and December are prone to breed pipe burst during a whole year; From 5：00 to 11：00 a.m.is a dangerous phase during a whole day; road crossings and the nearby are more likely to become the incident locations; cast iron pipes and concrete pipes are main materials during the pipe burst incidents. The most diameters of burst pipes are between DN300 to DNS00, and around DN1200. Cast iron pipes during such incidents are most between 20 to 30 years, while concrete pipes are most around 15 years.
