摘要
输电塔与电缆在竖向、侧向和纵向这三个方向的振动耦联方式是完全不同的,因而沿此三方向的抗震分析应相应采用不同的计算简图,当电缆的跨度和垂度大时尤应如此。文中从振动力学原理进行了简要论述,并举出了示意性的算例。
The coupling manners between the transmission line and its supporting towers during vibrations along the vertical, lateral and longitudinal directions are completely different. Thus, the computation schema for the earthquake-resistant analysis along these three directions are correspondingly different, espccially for the case of large spans and large sags of the transmission line. In this paper, some theoretical derivations are made and several illustrative examples are presented.
