本文通过对IEC 60826-2003以及GB50545-2010中关于风荷载的计算进行了深入的分析与对比，理清了这两个规范间差异。分析结果表明，IEC规范中地形系数是在计算基本风压时考虑，而GB规范中，地形系数是计算风压时，在风压高度变化系数中综合考虑的。虽然GB及IEC中都考虑了风压高度变化系数，但其具体取值存在较大的差异性。且荷载系数的取值大小以及考虑因素也不同。且GB规范以及IEC规范间的串用将会导致线路的造价大大增加，造成工程浪费。%By analyzing and comparing the calculation methods for wind loads in IEC 60826-2003 and GB50545-2010, the differences between the two specifications were clarified. In IEC standard, terrain coefficient is considered in the calculation of basic wind pressure, while in GB standard, terrain coefficient is considered in the calculation of wind pressure considering height variation. Although height variation factor of wind pressure are both considered in GB and IEC, the specific value has a big difference. The cross-using of GB and IEC standard in transmission line project would greatly increase the cost.
