摘　　要：[目的]旨在研究一种将海上风电导管架与养殖网箱结合的新型组合结构的水动力特性。[方法]通过物理模型试验,分析导管架与网箱组合结构的桩基水平荷载、网衣与导管架的连接张力,并考虑不同的水深、波高、周期、波向、流速和流向等参数对该结构带来的影响。[结果]试验结果表明,在0°规则波条件下,桩基最大水平荷载为30.2 N;在45°规则波条件下,桩基最大水平荷载为27.5 N;在正向波浪条件下(入射角为0°),桩基水平荷载比斜向波浪条件下(入射角为45°)的大9.5%。[结论]研究表明,在规则波条件下周期较小时网箱对导管架桩基水平荷载影响较小,在纯流条件下网箱显著增加了导管架的桩基水平荷载。[Objective]This paper proposes a novel structure that combines an offshore wind turbine jacket and aquaculture net cage,and its hydrodynamic characteristics are investigated.[Methods]Experimental tests are carried out to analyze the horizontal loads on the pile foundations of the combined structure,and the tension in the connection between the jacket and net cage,while considering the effects of water depth,wave height,wave period,wave direction,current velocity and direction,and other parameters.[Results]For 0-degree regular wave conditions,the maximum horizontal load on the pile foundations is 30.2 N.For 45-degree regular wave conditions,the maximum horizontal load on the pile foundations is 27.5 N.Thus,the maximum horizontal load on the pile foundations under 0-degree regular wave conditions is 9.5%greater than that under 45-degree regular wave conditions.[Conclusions]Under regular wave conditions,the net cage has little influence on the horizontal load on the pile foundations when the wave period is small,while under pure current conditions,the net cage will cause a significant increase in the horizontal load on the pile foundations of the combined structure.
