摘　　要：[目的]桶型基础是一种新兴的环境友好型海上风电基础结构,具有建造简单、施工高效、综合成本低等特点,逐渐受到了国内外海上风电工程界的关注和认可。桶型基础底部开口,可通过内部气垫的压缩产生的气压力排开水体,形成桶内外水压差来提供上浮力,这种自浮特性是桶型基础能够进行气浮拖航的前提。[方法]总结了国内外气垫结构的浮运特性,对比论述了应用于不同领域的气浮结构的相关理论、试验方法和研究结果。[结果]综述分析了气垫、分舱形式、谐振晃荡等对结构动力响应的影响规律。[结论]气浮拖航特性分析对桶型基础的推广应用具有重要的现实和理论意义。[Introduction]The bucket foundation is a kind of emerging environment-friendly offshore wind turbine foundation,with the characteristic of simple construction,high construction efficiency and low comprehensive cost.It has been gradually received attention and recognition from the offshore wind power engineering community.The bottom is an open structure,which can displace an amount of water by the air pressure generated by the compression of the internal air cushion,and form a buoyancy force by forming a water pressure difference between the inside and the outside of the bucket.This self-floating property is a prerequisite for the bucket foundation to perform air-floating towing.[Method]This paper summarized the floating characteristics of air cushion structures at home and abroad,and discussed the related theories,test methods and research results of air flotation structures applied in different fields.[Result]The influence law of air cushion,subdivision form and resonance sloshing on structural dynamic response is analyzed in depth.[Conclusion]The summary analysis of the air-floating towing characteristics of this paper has important practical and theoretical significance for the promotion and application of the bucket foundation.
