| 摘 要： | 特高压送电线路杆塔设计中,设计风速的合理取值关乎其结构安全。参照现行110～500kV送电线路风速取值及设计方法,提出了基于可靠性理论确定特高压送电线路杆塔设计风速的方法。首先确定目标可靠指标,然后确定设计风速相关参数,综合考虑可靠指标及经济指标后,确定设计风速最优参数。2条特高压送电线路杆塔设计风速的应用实例验证了该方法的有效性。

| Abstract: | In the design of towers for UHV power transmission line, selecting reasonable value of design wind speed concerns the structural safety of towers. Referring to the value of wind speed and design method given by existing design specifications for power transmission lines from 110 kV to 500 kV, a reliability theory based method to determine design wind speed for towers of UHV power transmission line is proposed. Firstly, the target reliability is determined; then the related parameters of design wind speed ar... |
