作为一种风敏感结构体系，塔—线输电结构在遇到强风条件下容易产生风振，给塔架结构安全性带来隐患，严重时易造成弯塔、倒塔事故。本文对“布—也”35kV 输电线路在极端恶劣大风条件下发生的24号铁塔倒塔原因进行了分析，并提出了几种铁塔升级、加固对策，旨在提高输电线路铁塔的可靠性和安全性。
作為一種風敏感結構體繫，塔—線輸電結構在遇到彊風條件下容易產生風振，給塔架結構安全性帶來隱患，嚴重時易造成彎塔、倒塔事故。本文對“佈—也”35kV 輸電線路在極耑噁劣大風條件下髮生的24號鐵塔倒塔原因進行瞭分析，併提齣瞭幾種鐵塔升級、加固對策，旨在提高輸電線路鐵塔的可靠性和安全性。

Tower-line power transmission structure can easily produce wind-induced vibration under the condition of strong wind as a wind-sensitive architecture,thereby bringing hidden danger to tower structure safety,tower can be bended and collapsed in serious condition.In the paper,reasons of No.24 iron tower collapse in ‘Bu -Ye’35kV power transmission line under strong wind conditions are analyzed,several iron tower updating and reinforcement countermeasures are proposed aiming at improving power transmission line iron tower reliability and safety.
