摘　　要：DL/T 5551—2018《架空输电线路荷载规范》对既有规范的荷载设计部分进行了修订,其中线条风荷载和杆塔风振系数的计算方法与旧规范相比存在较大变化。本文针对新规范的修订内容进行了提炼和总结,并对主要修编内容作了浅略解析,同时给出了风荷载设计方法修订后的影响,以期为新规范的顺利实施提供帮助。Load code for the design of overhead transmission line(DL/T 5551-2018)modifies the load design part of the existing specification.The calculation method of the wire wind load and the tower gust response coefficient is quite different from the old one.In order to make the implementation of the new code successful,this paper refines and summarizes the revised contents of the new code,and gives a brief analysis of the main revision content.At the same time,the impact of the revised wind load design method is given.
