摘要
以厦门海沧大桥西航道桥连续刚构弯箱梁为研究对象，建立空间结构模型，计算分析了连续刚构弯箱梁的动力特性，并探讨了曲率半径、薄壁墩的刚度等主要结构参数对其动力性能的影响，为该类桥梁的抗震设计研究提供了分析的基础．
The western approach bridge of Xiamen Haicang Bridge was taken as a research project. The space model of the structure was built up and the dynamic property of continuous curve box girder was calculated and analyzed. The influence of main structure parameters for the dynamic property was also discussed. A useful attempt about this type of bridge is made for a seismic design.
