摘　　要：采用闪电定位(ADTD)系统监测资料,对重庆轻轨采取防雷保护措施前后人员生命损失风险和经济价值损失风险进行了评估计算。结果表明,跨坐式单轨采取雷电防护措施后,人员生命损失风险减少了96.98%,经济价值损失风险减少97.38%。自重庆轻轨2号线实际运行以来,截止2009年,其5km范围内各站点及区间年均闪电达到了12 862.75次,但由于采取了有效的防雷措施,未发生一起雷击事故。Through an evaluation of life and economy losses caused by lightning in Chongqing light rail transit by using the monitoring data of ADTD lightning location system, it is clear that the losses of life and economy have decreased 96.98% and 97.38% respectively after the adoption of lightning protection system. Since the formal operation of Chongqing light rail transit Line 2, the yearly average lightning times have reached 12862.75 within 5 km of the line including all stops and sections. But there is no light- ning accident happening because of the perfect lightning protection measures.
