| 摘 要： | 以某220kV跨越输电塔为例,通过对跨越塔塔头布置形式的比较,主材一次变坡最优坡度的分析和二次变坡位置的优化,研究了不同外观设计对跨越塔塔重、基础作用力、根开等设计指标的影响。针对不同跨越塔塔型,计算了杆塔的振动频率,并基于随机振动理论计算了跨越塔的风振系数,发现不同塔型的风振系数加权值变化不大。

| Abstract: | Based on a 220kV long-span transmission tower,the effect on the design index such as tower mass,foundation forces and foot distance was studied through the comparison of the tower head arrangement, analysis of main member slope changing and optimization of second changing slope position.According to different long-span transmission tower types,the vibration frequency and the wind fluttering factor were calculated based on the random vibration theories.The weighted value of wind vibration coefficients are basically consistent. |
