摘要

2007年6月3日宁洱6.4级近城市直下型地震造成宁洱县供水管道严重破坏,供水网络瘫痪,全城断水。本文在震后宁洱供水系统灾害评价和科学考察的基础上,总结了此次宁洱地震供水系统震后应急抢修的经验和教训。查找城区管网的破坏点可以充分发挥专业管道探测设备的优势。震后采用关闭阀门分段检查,重点查找存在地表永久变形的区域,是快速确定供水主干管道漏水点的较佳方案。
An earthquake of M6.4 struck the county of Ning'er shortly after 5:30 a.m.June 3,2007,the quake damaged pipes severely,cutting off water supplies.Based on the disaster evaluation of water supply system and the scientific investigation on site,the experiences and lessons of post-earthquake emergency response are summarized in this paper.Location for the leakage point of water pipeline in city area can take the full advantage of the professional pipeline detection equipment.For the location of main pipeline leakage point,it is suggested that more attention should be paid to the area with the permanent ground deformation after the closure of valves.
