摘　　要：矮寨特大悬索桥跨高330m,为跨峡谷的世界第一高桥,跨径1176m,主跨为亚洲第一大桥。为便于广大游客登上大桥观光,修建了73m高的吉首矮寨大桥观光电梯。观光电梯所在地质为卡斯特地貌,土壤电阻率高达9000Ω·m。由于吉首市属多雷暴区域,矮寨大桥电梯和城市办公楼、商品房的电梯不同,防雷工作具有很强的特殊性和复杂性,笔者针对矮寨大桥观光电梯的特殊结构进行了科学合理的防雷设计、施工分析。竣工后,经过湘西州防雷中心的武汉康达大地网测试仪检测,防直击雷部分电阻达到3.8Ω。Heavy aizhai suspension bridge across a 330 meters high. is across the vallevs of the world＇s first takahashi, span 1176 meters, mainspan first hridge in Asia. To facilitate the broad masses of tourists on the bridge, built the 73 - meter-- high jishou aizhai hridge sightseeing elevator. Sightseeing elevator for in geological Custer landform, soil resistivity is as high as 9000Ω, m. As jishou city more thunderstorms area, aizhai bridge elewflor office buildings, commercial housing and the city of elevator, lightning protection work Ires a slrong particularity and complexily, the autlhor in view of the spet＇ial struelure of aizhai bridge sightseeing elevator for scientific and rational analysis of the lightning prolection design and conslrtue- tion. Completed, after Suggestions for lightning protection cenler of wuhan kangda geodetic network lesler, prevent direct lighning part 3.8Ω resis- tancee.
