摘要
在地震作用下,大跨越自立式高压输电塔-电缆体系是一种复杂的空间塔-缆耦联振动体系,工程中需要一种合理的抗震计算简图。本文是文献工作的继续,对60KV线路的某输电塔进行了研究,建立了塔-缆耦联振动的力学模型,采用作者编制的TCCV89计算机程序进行了地震反应分析,得到了一些有意义的结果。本文结果可推广到具有n层电缆的输电塔。
Under the action of earthquake , the high voltage system consisting of long span transmission lines and their supporting towers is a complicated system of spatial coupling vibration. It is necessary to determine the reasonable computation scheme of this System for engincering design. In this paper, a System composed of 60KV transmission lines and their supporting toweis is analyzed. The present study continues the work of Rcference[1]. The mechanical models of the tower-line coupling vibration are given and the equations of vibration are derivcd. Some results with practical significance are obtained referring to the Systematic earthquake response analysis by use of TCCV 89 computer programme. The method presented in this paper can be further cxtended to the System consisting of n-row lines and their supporting towers.
