摘　　要：青藏铁路格拉段是世界上海拔最高的高原铁路,雷击过电压保护面临高原和冻土两大难题。针对雷击过电压的影响因素,在分析格拉段雷暴活动情况及沿线高原冻土地区地质特点的基础上,提出铁路沿线防雷接地工程的实施办法。结合高原冻土地区的特点,探讨了格拉段防雷接地技术的新思路和急需解决的问题。The QinghaiTibet Railway is a highland railway with highelevations, its lightning protection as concerned as highland and frozen soil is left to be researched. Grounding in tundra is the key technology of lightning protection based on the analysis of thunderstorm and geology status on site. Some new methods of grounding for lightning protection in tundra to be tested and problems still to be settled are presented.

关 键 词：雷击过电压保护 防雷接地 雷暴活动 冻土 冻土地带
