中文摘要：

畸形波是一种瞬时存在、具有较大波高的灾害性波浪，对近岸和海洋工程结构物都具有较大的破坏性。文中首先从畸形波的定义入手，通过分析畸形波的发生机理，引入畸形波模拟的探讨，总结畸形波对近岸构筑物作用的研究现状与发展趋势，并提出需要进一步研究的课题。

英文摘要：

Freak waves are both extremely large waves and highly transient in space and time. Such a wave may lead to dam- age of coastal and ocean engineering. The paper explores simulating of freak wave by analyzing its definition and occurrence mechanism. Moreover, the paper summarizes the existing research and development tendency of freak wave action on coastal structures, and then puts forward the need to further research topic.
