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及其与国内规范的异同,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,对印度输电线路规范IS 802和中国输电线路规范GB 50545-2010的风荷载计算进行分析和比较。结果表明,中印规范在风荷载重现期、平均时距、风载体型系数、风振系数以及线路和杆塔风荷载计算值上都有些差别。With increasing requirements for designing overseas projects,it is necessary to understand and master foreign engineering codes and differences between those codes and Chinese codes.Based on practical engineering projects,this paper presents a comparative study on the wind load calculations of an overhead transmission line by Indian IS 802 and Chinese GB 50545-2010 for the power transmission line project,respectively.The study suggests that there are some differences in the wind load return period,average wind speed time interval,drag coefficient,and calculated loads on the conductor and steel tower between Indian codes and Chinese codes.
