摘　　要：面对越来越多的国外工程设计的需求,了解、熟悉并掌握国外规范与国内规范的异同,对于在国外工程中更好地采用国外规范进行设计是很有必要的。从实际工程出发,选取国外三本主流输电线路设计规范,与我国规范GB 50545-2010的风荷载计算进行分析和比较。结果表明,国内外规范在风荷载重现期、平均时距、风载体型系数、考虑动力特性的系数以及线条和杆塔风荷载计算值上都有差别。所得结论可供工程设计人员参考。As increasing market of designing oversea project,it is necessary to comprehend and master foreign codes.Based on engineering practice,calculation methods of transmission line wind load in four codes at home and abroad are compared.The conclusion is there are differences about return period of wind load,average wind speed time interval,drag coefficient,gust factor,calculated wind load on the wire and tower in the codes at home and abroad.
