摘　　要：海上漂浮式风力机支撑结构动力载荷的确定不仅对于结构设计、施工过程非常重要,对于设施的运维保障同样重要。水动力载荷的计算可归为基于势流理论的理论模型和基于计算流体动力学的数值模型两类方法。本文简述了两类模型各自的基本原理,明确其优劣,为实际工程应用的合理建模提供参考。对于海洋工程,水池物理模型实验发挥着重要作用。本文以某结构型式的浮式支撑结构的物理模型实验为例,阐述了物理模型实验技术的局限性及改进措施,为工程建设提供必要的技术支撑。The floating offshore wind plant has grown rapidly in the past decades facing the demand of green energy resources.Compared to the onshore wind plant,the offshore wind plant is more challenging because of the harsh oceanic environment.The hydrodynamic loads are needed to be accurately quantified not only for the design of platforms but also for the routine maintenance.The methods to calculate the hydrodynamic loads are classified as the method based on potential theory model and the method based on computational fluid dynamics(CFD)model.The principles of the models are briefly introduced to highlight the different usability.Besides of the numerical methods,the physical experiments contribute to explore the dynamic loads and the structural optimization.The main technologies of physical experiments are briefly outlined by means of a study case.The paper focuses on presenting the methods on quantifying the hydrodynamic loads on the floating platform in order to promote these methods in practical engineering.
