摘要： 以广州地铁十四号线轻轨高架桥为研究背景，通过脉动测试及列车运营测试分析，重点研究了一联三跨柔性薄壁高墩连续刚构桥的动力特性及动力响应。结果表明：桥梁实测基频2.197Hz大于设计值1.794Hz，桥梁刚度满足要求；柔性薄壁边墩的动力响应对列车运行速度不敏感，且列车刹车及会车状态下不是桥梁柔性薄壁边墩最大受力状态。

Abstract: Taking the light rail overpas of Guangzhou Metro Line No.14 as the research background, through the pulsation test and metro operation test analysis, the results show that the measured fundamental frequency of the bridge is 2.197Hz, which is greater than the theoretical value(1.794Hz）, and the stiffness of the bridge reaches the requirements; the dynamic response of the flexible thin-walled side pier is not sensitive to the train speed, and maximum force state of flexible thin-walled side pier is not at the time of train braking and meeting status.
Key words: flexible thin-walled pier, continuous rigid frame bridge, light rail, dynamic response
