大跨越输电塔-导线体系与一般的土木工程结构不同,最显著的特点是它由导线和各个钢塔连接而成的连续体.在地震作用下,由于相邻塔架的相互影响,输电塔-导线体系是一种复杂的空间塔-线耦联振动体系,对它进行精确计算十分困难而且复杂.本文在文献[1]和[2]的基础上,给出该种体系更一般的动力分析计算简图,导出了振动方程.最后结合具体例子,分析了该体系的自振特性,并与实测结果进行了比较.
The major difference between the transmission tower-conductor system and the general civil engineering structure is the continuum formed by the connection between the conductor and each steel tower. Under the action of the earthquake, due to the mutual influence of adjacent towers, the transmission tower The conductor system is a complicated space-tower-line coupled vibration system, and it is very difficult and complicated to calculate it accurately. This article gives a more general power of the system based on the literature [1] and [2]. Analyze and calculate the diagram and derive the vibration equation. Finally, with the specific examples, the natural vibration characteristics of the system are analyzed and compared with the measured results.
