中文摘要：

松原二桥引桥为连续梁桥，抗震设防烈度为8度，文章以其中一联引桥为例介绍了引桥的抗震设计过程。分别采用延性抗震设计和减隔震设计两种思想对该桥纵桥向进行了计算分析，并通过对减震装置力学参数的优化分析得出了合理的减隔震措施。通过对两种抗震设计思想的设计结果进行比较，提出了最终的抗震设计方案。

英文摘要：

A practical seismic design of the continuous girder bridges under extreme severe seismic excitation was presented in this paper. The whole seismic design was presented by the example of a unit of continuous girder bridge. Ductility design and isolation design were analyzed and compared, mechanic parameter of isolation device was studied, the proper aseismic measures were accordingly recommended in the end.
