摘要
研究一种新型220/110 kV混压四回路Q460高强钢管窄基四柱塔,通过考察杆塔结构用钢量、顶点挠度及结构自振频率对铁塔根开、节间进行优化分析,提出220/110 kV混压四回路窄基钢管塔合理根开、节间的选取方法及取值。
This paper studied a new type of Q460 high-strength narrow-base four-column steel pipe tower for 220/110 kV mixed voltage 4-circuit Transmission line. Examining the steel consumption, vertex deflection and natural frequency of structure, the structural optimization and analysis on leg spans and beam intervals are carried out. The reasonable values and selection method of the leg spans and beam intervals of 220/110 kV mixed voltage 4-circuit narrow-base steel pipe tower are proposed.
