摘　　要：以"彩虹"台风线路倒塔事故为背景,探讨输电线路事故复核标准及计算方法,对发生受损的220 kV输电线路进行台风风速工况下的铁塔受力计算,分析导致架空输电线路在台风吹袭时发生倒塔事故的要因,给出相关结论及建议。This paper is based on the background of towers collapsing accidents of overhead transmission lines during ttCaiHong〉 ,ty-phoon. The criterion on design reviewing of existing towers is discussed, and the wind load acting on the damage towers of the 220 kV overhead transmission line from typhoon attacking is calculated, as well as the reason for the tower collapsing was analyzed. Fi-nally ,some conclusions and suggestions are proposed to enhance design standards and tower strength on the coastal zones where ty-phoons landing always recur.
