| 摘 要： | 本文将我国最新输电线路设计规范GB50545-2010与ASCE规范、IEC60826规范、英国规范BS8100作了对比,分析了体型系数、风压高度系数等相关参数的计算取值,并结合实际工程算例对线条风荷载及塔身风荷载进行计算。对比结果表明:总体来看,我国规范计算得出的线条风荷载以及塔身风荷载并不低于国外规范值,新规范提高了送电线路的重现期,增大了设计的安全余度。

| Abstract: | The different methods of wind londing definition between Chinese new code, which will be launched in July 2010, and the ASCE standards, IEC 60826, the British standard BS8100 were discussed in this paper. Based on the calculation and comparison of related parameters and wind loading in a real project, it can be concluded that the wind loading defined in the Chinese new code is no less than those calculated by other codes, and also the return period has been raised up in the new code to improving the design security. |
