摘要/Abstract

摘要： 筒型基础是近年来在海上能源开发的主要基础形式之一。采用水动力分析软件MOSES建立了三筒型基础结构的数值分析模型，对不同吃水、不同水深以及不同筒位布置的水动力系数和幅频响应特性进行了研究。结果表明：吃水和筒间距对结构的水动力系数和运动响应的影响明显大于水深的影响，在结构设计中合理的筒位布置以及施工过程中调整吃水深度能够保证良好的运动响应特性。

关键词: 海洋工程；港口工程；筒型基础；吃水；间距；水深；运动响应

Abstract: Bucket foundation is one of the main patterns of foundation for development of offshore energy in recent years. The numerical analysis models for three bucket foundations (TBF) were established by the hydrodynamic analysis software MOSES. The hydrodynamic coefficients and amplitude-frequency responses characteristics with different drafts, water depths and arrangements of bucket position were studied. The results show that: the influence of draft and bucket spacing on hydrodynamic coefficients and motion responses is significantly greater than that on water depth. The reasonable arrangement of bucket foundation in design and adjustment of draft during construction can ensure good motion response characteristics.

Key words: ocean engineering; port engineering; bucket foundation; draft; spacing; water depth; motion response
