针对某500 kV输电线路工程，考虑微地形（气象）区域的设计风速增大情况（35 m/s左右），对安装粘弹性阻尼器（viscoelastic dampers，VED）前后的典型酒杯塔进行模态分析、动力时程分析和静力分析。结果表明，安装VED后，酒杯塔基本自振周期延长了143%；风振系数降低幅度呈先增加后减小的趋势，在铁塔横担处降低幅度最大为281%；主材内力减少约14%；计算塔质量减少5%左右。由此可见，VED减振效果明显。

Aimed to a 500 kV power transmission line project, considering the design wind velocity increase (about 35 m/s) in micro-topography or microclimate region, the modal analysis, dynamic time-history analysis and static analysis are carried out on the cup-type power transmission tower with or without viscoelastic damper (VED), respectively. The results show that the natural vibration period of the tower increases by 14.3% after using VED; the wind vibration coefficient first increases, then decreases, with the maximum value of 28.1% appearing at the tower cross arm; the pressure of main material deduces about 14%; the calculated tower weight reduces about 5%. Therefore, the vibration control effect of VED is obvious.
