摘　　要：参照同类连续梁桥确定初步的结构方案,利用有限元分析软件ANSYS对连续梁桥模型进行静力分析。在静力分析基础上对模型进行动力学研究,得到了连续梁桥的固有频率和振型特征,然后通过谐响应分析得到了连续梁桥在不同激励下的动力响应。结果表明,分析所得的结果与实际吻合,为进一步研究连续梁桥的其它特性和结构优化提供参考。Initial structural scheme of the continuous beam bridge was determined by reference to similar ones, static analysis was made on the bridge model by use of finite element analysis software ANSYS. Kinetic studies were then conducted to gain natural frequency and vibration characteristics. And finally the bridges dynamic responses under different exitations were achieved through harmonic response analysis. The results indicated that the data examined agreed with actual ones, which would surely benefit further research on other features of continuous beam bridge and structure optimization.
