摘要

针对双柱悬索拉线塔线体系与自立式特高压输电塔线体系风振特性显著不同，为研究双柱悬索拉线塔塔线体系风振响应随风向角及风速变化，进行单塔、塔线体系气弹性模型风洞试验。结果表明，塔线体系风振响应随风向角变化规律基本与单塔试验相同，但变化幅度明显高于单塔。0°、45°、60°风向角为工程设计不利工况。

Abstract

The wind-induced responses of cross-rope suspension tower-line is dramatically different from the self-supported UHV transmission tower-line. An aero-elastic wind tunnel test was used to investigate the wind-induced response of cross-rope suspension tower-line, changing with wind direction angle and the test velocity, both single tower model and tower-line coupling system model was carried out. Results indicate that the dynamic response of the tower-line coupling system model, changing with wind angle, works in the same law with the single the tower model, but the amplitude is apparently bigger than the single the tower model. 0°, 45°and 60° should be considered as the extreme conditions in the design process.
