摘　　要：国内外特别是我国近些年跨海桥梁建设发展迅速,鉴于1995年日本Kobe地震中存在跨海桥梁损伤的案例,如东神户大桥和明石海峡大桥(地震时未完工),因此跨海桥梁的地震安全问题显得尤为重要。目前,桥梁抗震问题的研究与总结主要集中于陆上桥梁,针对跨海桥梁的抗震设计方法与研究相对较少。归纳了世界范围内经受地震考验的跨海桥梁的震害表现,通过分析国内外不同历史时期几座典型跨海桥梁的抗震设计和减隔震技术的应用,总结了跨海桥梁抗震技术的发展与主要成果。The sea-crossing bridge has been developed rapidly during the past decades. However, seismic damages of the sea-crossing bridge have been reported frequently, such as Akashi Kaikyo Bridge （under construction during the earthquake） the damages of the in Kobe earthquake Higashi Kobe Bridge and in Japan in 1995. Therefore, it is of great importance to focus on its seismic safety. At present, the research and summarization of the seismic problems of the bridge are mainly concentrated on bridges on land, and the seismic desi method and research for the offshore bridges are relatively limited. The seismic damages of the sea-crossing bridges all over the world have been summarized in this article. This study concludes the state of the earthquake resistance technology of seacrossing bridges, based on seismic design and application of seismic mitigation and isolation technique for some typical sea - crossing bridges during different periods of history in the world.
