摘　　要：为详细研究中美设计规范在导地线风荷载和并何在计算方面的差异,介绍了中美两国输电线路荷载设计规范,从线条风、冰荷载计算公式出发,对基本风速、风压高度变化系数、风荷载调整系数、覆冰厚度等参数进行研究,对比线条风、冰荷载计算的异同点。算例结果表明,中美两国规范在导地线风、冰荷载计算值上都存在差别,为工程设计提供了参考。In order to make comparison with both wind and ice load in Chinese and American load design codes. The Chinese and American load design codes of transmission lines are introduced in this paper. The parameters such as basic wind speed, velocity pressure exposure, gust response factor and ice thickness are studied based on the calculation formulas of wind and ice load. The similarity and difference of wind load and ice load of lines are compared. The result shows that the comparing calculation values of both wind and ice load are different. It pro- vides reference for project design.
