中文摘要：

进行了大跨越输电塔-导线耦联体系的振动台试验,用以检验所提出的输电塔-导线耦联体系理论计算模型和方法的合理性和正确性.试验结果表明,在纵向和侧向振动情况下,最大加速度地震反应的理论值和试验值的误差均在可以接受的范围以内,说明所提出的输电塔-导线耦联体系的理论计算模型是合理的.从理论计算结果和试验结果的误差分析可知,侧向振动情况下的输电塔理论计算模型要比纵向情况下的精确一些.导线对输电塔地震反应的影响较大,在实际计算中不可忽略.塔架与导线之间存在的耦联作用越显著,导线对输电塔地震反应的影响越大.

英文摘要：

In this paper, a shaking table test of coupled system of transmission lines and towers is carded out to demonstrate the validity of the theoretical computational model of transmission tower systems proposed by the authors. The results show that the errors between theoretical and experimental maximum accelerations are acceptable in both in-plane and out-of-plane cases of vibration, which indicates the theoretical computational model is reasonable. The out-of-plane model is found more accurate than the in-plane one by analyzing the errors and comparing the theoretical calculation with the results of test. The effects of transmission lines on the seismic response of the transmission towers are obvious and can not be ignored. The stronger the coupling effects between lines and towers are, the greater the effects on the seismic response of the transmission towers will be.
