针对实桥模型进行有限元模拟,运用反应谱法在模型中输入动力特性值运行分析,得出桥梁基本自振频率为6.214Hz,基本周期为1.011s,以及结构的部分自振频率及振型,并在水平和竖向地震作用下,进行了桥梁墩身部分的抗震计算,为桥梁在抗震安全性方面的分析提供参考依据。

In this paper, a finite element model was adopted for the seismic responses analysis of a long - span prestressed concrete bridge. Response spectrum method is used to run the analysis of dynamic characteristics in the horizontal and vertical seismic force for obtaining model response spectrum characteristic values and the mode shapes, which can provide a reference in the analysis of seismic safety.
