摘　　要：厦漳跨海大桥北汊主桥是主跨780 m的连续钢箱梁双塔斜拉桥,抗震设计非常复杂,且无规范可循,必须开展专门研究。从抗震设防标准、地震激励方式、塔(墩)梁连接方式、地基状况、阻尼器选型等方面对厦漳跨海大桥北汊主桥抗震设计研究进行介绍,为类似桥梁设计提供参考。North branch main bridge of Xiazhang Oversea Bridge is a continuous steel box girder double- pylon cable- stayed bridge at main span of 780m, the seismic design is quite complicated and no specifications are followed, so specialized research must be developed. This paper introduces research on seismic design of north branch main bridge of Xiazhang Oversea Bridge from the aspects of seismic fortification criteria, earthquake incentive methods, connection modes of pylons （piers） and beams, foundation conditions and tvoe selection of damners, etc. and nravides a reference for design of similar bridges.
