摘　　要：由于输电线路具有传输线路长、易受周围环境影响等特点,因此输电塔线的风致响应一直是一个研究热点问题。而输电铁塔与导线具有一定的耦合作用,当输电塔线收到风荷载的作用时,该耦合作用可能会对输电塔线产生不利影响。为解决上述问题,本文重点关注了输电塔线耦合作用对最不利风向的影响,并进行了仿真计算,本文所得结论对后续输电塔线风致响应提供了一定的理论参考。Due to the characteristics of long transmission line and easy to be affected by the surrounding environment,the wind-induced response of transmission tower has always been a hot topic.The transmission tower and the conductor have a certain coupling effect,when the transmission tower line receives the wind load,the coupling effect may have adverse effects on the transmission tower line.In order to solve the above problems,this paper focuses on the influence of transmission tower line coupling on the most unfavorable wind direction,and carries out the simulation calculation.The conclusions of this paper provide a certain theoretical reference for the wind-induced response of subsequent transmission tower line.
