摘　　要：借助互联网平台信息迅速及时的特点,本文收集和整理了2012年国内媒体报道的给水爆管事故。统计数据中,南方沿海城市较多;冬季爆管次数较多,主要集中在1月、2月和12月,而夏季7月份爆管也较频繁;一天当中5-17时段内爆管的次数较多;在交通主干、道路路口和交叉口位置爆管事故较多。通常认为管道老化和施工造成的爆管是爆管事故的主要原因;爆管管径集中在DN300-DN600、DN800和DN100-DN1200区间,其中DN600管道发生爆管次数最多;管材为铸铁管、水泥管,管龄在20-30年的管道爆管次数较多。By means of the Internet platform information which is rapid and timely, the relevant data of burst events of water distribution system reported by domestic media in 2012 were collected and collated. The statistics showed that burst mainly occurred in the southern coastal cities; winter was the main season for burst, especially in January, February and December; in July burst was also frequent; 5：00-17：00 was a dangerous phase during a whole day; the trunk road intersection or crossings and the construction site were more likely to become the incident locations. It is generally accepted that improper construction and aging were the main reasons for burst. The diameter of burst was concentrated in DN300-DN600, DN800 and DN1000-DN1200, especially in DN600. Pipes of cast iron pipes and cement pipes, and pipes pipeline in 20-30 years old were more likely to burst.
