摘　　要：青藏铁路格拉段是世界上海拔最高的高原铁路。开展沿线雷暴活动情况的研究,掌握在高原气候和海拔的双重作用下,其独特的雷暴活动规律,对于雷击过电压保护具有重要意义。结合沿线多年勘测的雷暴数据进行了理论分析,总结了沿线的雷暴活动情况及雷电流特性,为深入开展沿线雷击过电压保护、实施防雷接地工程打下基础。Gela Segment of Qinghai-Tibet Railway is state key project. As a highland railway with high-elevation, doing research under the condition of thunderstorm, grasping the unique thunderstorm regular pattern based on local climate and elevation, is necessary for lightning protection. The paper analyzes the thunderstorm condition and characteristics of thunder current combined with plentiful data of reconnaissance along the line, provides basis for succedent research on lightning protection technology.
