摘　　要：采用不同拉压模量理论,建立了不同模量混凝土桥面板结构的动力非线性有限元算法,编制了相应的非线性有限元计算程序,对广东金马大桥主梁的桥面板进行了动力特征分析和动力时程分析,得出了一些有价值的结论,这种计算方法可以为同类工程的数值计算提供参考.The theory of the different extension-compression elastic modulus was adopted to establish the dynamic nonlinear FE algorithm for the concrete bridge deck slab of different elastic modulus, and the nonlinear FE program was compiled. The dynamic mechanics properties and the time history analysis of the Jinma Bridge were carried out for its slab of girder with the algorithm proposed in the paper, which can be the reference to the similar structures calculating. Some important conclusions are obtained.
