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．
Taking the XCMG continuous curved box-girder of Xiamen Haicang Bridge as the research object, the spatial structure model is established and the dynamic characteristics of the continuous rigid frame bending box girder are calculated and analyzed. The main structures such as the curvature radius and the rigidity of the thin- The influence of parameters on the dynamic performance of the bridge provides the basis for the analysis of the seismic design of such bridges.
