摘要: 对比了不同版本的架空配电线路规范关于重现期、基准高度和最大设计风速的规定,可知配电线路在防风方面的设计标准逐步得到了提升。然后通过计算典型的直线杆和转角杆,结果表明现行规范下钢筋混凝土杆的底部弯矩设计值增大,文章最后提出若干配电线路防风措施。Abstract: The standards of different versions on return period, reference height and maximum design wind speed for overhead distributed net were compared in this paper. This comparison showed that the design standards on windbreak of designed distributed nets have been gradually advanced. Then, the calculation for the typical straight-line pole and the angle pole showed that in this current standard, the design base moment of the reinforced concrete pole has been increased. Finally, some measures of windbreak for distributed nets were advised.
