摘要:
为了研究地震作用下特高压塔线耦联体系导线、地线的非线性振动响应,文中以单向和双向一致激励为主,通过输入不同加速度幅值的El Centro波、Taft波、Pasadena波及上海人工波,对某型特高压输电塔线耦联体系进行了缩尺模型振动台试验。试验主要分2种工况:将导线作为集中质量进行计算的方法以及挂有实际分裂导线模型的方法。试验结果表明:两种体系中塔体结构动力特性存在差别;地震作用下,挂线单塔各项动力反应峰值比相应的单塔悬挂集中质量有不同程度的降低,8度罕遇地震时较为显著,导线的非线性振动效应有利于该型输电塔动力反应幅值的降低。挂线单塔与挂集中质量单塔不同方向的加速度能量谱分布规律存在较大差异。
Abstract:
In order to study the nonlinear seismic responses of transmission tower-conductor coupling system ,shaking table tests on 1 000kV UHV transmission tower-line coupling system were carried out subjected to four types of ground motions with different peak ground acceleration in one direction and bi-direction. Two types of model were tested, including tower-conductor coupling system and independent tower with lumped mass to simulate the conductors. The results show that there are some differences in the vibration properties between these two structures. Seismic responses of the tower in the coupling system have been reduced compared with that of its counterpart, especially in the case of input ground motions with high seismic intensity due to the nonlinear vibration responses of the conductors. There is a big difference in the acceleration energy spectrum between the two structures in both cross-line and along-line directions.
