由于大跨径索吊桥的轻、柔、低阻尼的特点，桥梁的风振问题成了结构设计及施工过程中所关注的热点。本文讨论了大跨径索吊桥的振动信号的特点及信号采集与处理的方法，以广东虎门大桥作为研究对象．过行了桥梁动态特性试验，安装与不安装TMD的抑振对比试验．并分析了TMD的抑振效果。
Due to the light, soft and low damping characteristics of the long-span cable-stayed bridge, the wind-induced vibration of the bridge has become a hot spot in the structural design and construction process. This paper discusses the characteristics of vibration signal and the method of signal acquisition and processing of long-span cable-stayed suspension bridge. Taking Humen Bridge in Guangdong as the research object. Passed the bridge dynamic test, with or without TMD damping comparison test. The anti-vibration effect of TMD is analyzed.
