某特高压线路钢管塔板件开裂原因及微风振动防治措施

Analysis on Cracking Causes of Steel Tube Tray of an UHV Line and Research on Prevention Measures of Breeze Vibration

为了从根本上预防和治理钢管塔微风振动问题,从设计、加工、安装等方面简要分析某高压线路钢管塔板件开裂的原因,并从结构设计的角度提出钢管塔微风振动的预防措施,同时根据以往研究成果以及工程应用经验,对运行线路钢管塔的微风振动给出具体的治理措施。

In order to prevent and control the wind vibration of steel tube tower fundamentally,this paper briefly analyzes the reasons for the cracking of steel pipe tower plates of a high-voltage line from the aspects of design,processing,and installation,and proposes preventive measures for the breeze vibration of steel pipe towers from the perspective of structural design.Based on previous research results and engineering application experience,The breeze vibration of the steel tube tower gives specific treatment measures.
