采用塑性铰模型、动力弹塑性分析法对罕遇地震连续梁桥抗震性能进行了分析，揭示了罕遇地震作用下桥梁受力及变形情况， 并对各墩柱的抗震能力进行了评价，为桥梁的抗震设计提供依据。

Elements with concentrated plastic hinge were adopted for the analytical mode1,study of seismic behavior of continuous beam bridge was performed with dynamic elastic-plastic analysis method, The analysis results show the variation of force and deformation under seismic load, the seismic resistance performance evaluation of each pier also were discussed in this paper, the results can provide references to the seismic design of similar bridge.
