本报告旨在为青马大桥建立一个三维动态有限元模型，了解大桥模态振动的主要特征，并与实测的固有频率和振型进行比较。特别感兴趣的是振动模式之间的相互作用，主跨和边跨之间的相互作用，以及缆索、桥面和塔架之间的相互作用。正如Abdel-Ghaffar（1978）对圣佩德罗-终端岛大桥、巴克兰等人（1979）对金门大桥和Kumarasena等人（1989）对鹿岛大桥所做的那样，数值模拟和全尺寸测量的结合提供了对青马大桥行为和特性的全面理解。
This paper focuses on the development of a three-dimensional dynamic finite element model for the Tsing Ma Bridge, the understanding of the main features of modal vibrations, and the comparison with the measured natural frequencies and mode shapes. Of particular interest are the interactions between vibrational modes, between the main and side spans, and between cables, deck, and towers. As done by Abdel-Ghaffar (1978) for the San Pedro-Terminal Island Bridge, Buckland et al. (1979) for the Golden Gate Bridge, and Kumarasena et al. (1989) for the Deer Isle Bridge, the combination of numerical modeling and full-scale measurement provides a comprehensive understanding of behavior and properties of the Tsing Ma Bridge.
