| 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,场地地震基本烈度高达Ⅶ度,其抗震设计非常复杂,且无规范可循,为此开展专门研究.以JTG/T B02-01-2008《公路桥梁抗震设计细则》为指导,从抗震设防标准、地震动输入、动力有限元建模、抗震性能评价、抗震构造措施检查等方面,对厦漳跨海大桥北汊主桥抗震性能研究进行介绍,为类似桥梁抗震设计提供参考.

| Abstract: | Main bridge in northern bay of Xiamen-Zhangzhou Crossing Sea Bridge is a continuous steel box girder twin-tower cable-stayed bridge with 780m main span,the basic seismic intensity is up to VII degree,so anti-seismic design is very complicated and no specifications are followed.For this reason special research must be developed.This paper under guidance of JTG/T B02-01-2008 "Detailed Rules for Anti-seismic Design of Highway Bridges" introduces research on seismic performance of main bridge in northern bay of Xiamen-Zhangzhou Crossing Sea Bridge from aspects of seismic fortification criteria,dynamic seismic input,dynamic finite element modeling,evaluation for seismic performance and check of seismic structure measures,etc.to provide a reference for seismic design of similar bridges. |
