| 摘 要： | 针对大足县城南中学附近建设移动通信基站后频遭雷击的状况,结合2006—2009年重庆地区ADTD闪电定位系统监测资料,重点分析该校频遭雷击事故原因。结果表明:移动通信基站建设(增加了遭受直击雷和雷击电磁脉冲影响概率)是城南中学频遭雷击的诱因;该校未安装防雷装置,且部分教学楼处于铁塔保护范围外,而位于雷击铁塔的散击区内,是频遭雷击的直接原因。

| Abstract: | The causes of frequently occurred lightning accidents in the Chengnan Middle School of Dazu County,Chongqing after a mobile communication base station was constructed are analyzed by means of the monitoring data of the ADTD lightning location system in Chongqing from 2006 to 2009.The results show that the construction of the mobile communication iron tower increased the lightning strike probability of the Chengnan Middle School and the influence of lightning electromagnetic impulses,which is the major cause of the frequently occurred lightning accidents.The teaching building frequently stroke is out of the protective range of the iron tower,located in the lightning scattered strike zone of the iron tower,and does not have lightning protection devices. |

| Keywords: | communication base station lightning-induced disaster lightning strike probability shielding failure rate scattered strike zone |
