摘要
对沈阳地区跨越浑河的60KV线路的输电塔进行了研究。建立了塔一缆纵向耦联振动的力学模型,推演了在地震作用下此模型的振动方程,采用作者编制的TCCV89计算机程序进行了地震反应分析,其结果可推广到具有几层电缆的输电塔体系。
This paper studies the system consisting of 60kv transmission lines and their supporting towers across the Hunhe river in shenyang area, establishes the mechanical model of tower-line coupling vibration, derives the model's vibration equation which is under earthquake action and carries out the earthquake response analysis using the computer program. The result of this study can be extended to the system of transmission towers with n-layer cables.
