为分析桥墩形式对大跨度连续刚构桥的地震影响，以某连续刚构桥为工程背景，运用大型专业有限元分析软件MIDAS CIVIL建立动力分析模型，分别对不同墩截面形式进行模态分析，采用动力反应谱分析法计算出结构的动力响应，并对不同结果对比分析，所得结论为大跨度连续刚构桥的抗震分析和设计提供相关依据。%In order to analyze the influence of bridge pier form on the large-span continuous rigid frame bridge, a continuous rigid frame bridge is used as the engineering background, and the dynamic analysis model is established by using the finite element analysis software CIVIL MIDAS. The model analysis of the different pier section is carried out. Dynamic response spectrum analysis method is used to calculate the dynamic response of the structure, and the results are compared and analyzed. The results provide a basis for the seismic analysis and design of large span continuous rigid frame bridges.
