摘　　要：桥梁工程是保证国民经济发展的主要交通设施,在抗震救灾中更是具有关键性作用.论述了海啸的成因及其破坏特点,探讨了海啸对桥梁上部结构和下部结构的破坏、海啸与桥梁的共振破坏,提出了桥梁工程抵御海啸袭击的对策.Bridge is the main transport facilities guaranteeing the development of national economy, which has a key role in earthquake resistance and disaster relief. In this paper, the causes and characteristics of tsunami are discussed, and the risk of tsunami in coastal areas are analyzed, and the damage of tsunami to bridge substructure, bridge superstructure and tsunami resonate with the bridge are investigated. Finally, the countermeasures of bridge structures resisting tsunami＇s attack are proposed.
