摘要	风、浪载荷是海上单桩风机主要承受的环境载荷，在风、浪作用下风机塔顶会产生振动，风机桩基产生交变应力等动力响应，为了研究北部湾海域海况下单桩风机在环境载荷作用下海上单桩风机的动力响应，本文根据北部湾海域条件为边界条件通过ANSYS APDL进行有限元建模，并设置风机工作和自存两种工况，分别从风载荷、浪载荷和组合载荷作用下分别对风机的动力响应进行研究，得到单桩风机在风、浪作用下的动力响应，及风、浪作用在单桩风机的耦合机理。
Abstract	Wind and wave loads are the main environmental loads borne by offshore single pile fan. Under the action of wind and wave, the top of the fan tower will vibrate, and the pile foundation of the fan will produce dynamic responses such as alternating stress. In order to study the dynamic response of single pile fan under environmental loads in the sea conditions of the Beibu Gulf, In this paper, finite element modeling was carried out by ANSYS APDL according to the boundary conditions of the Beibu Gulf sea area, and two working conditions of the fan were set up and self-storage. The dynamic response of the fan under wind load, wave load and combined load were studied respectively, and the dynamic response of the single pile fan under wind and wave action and the coupling mechanism of wind and wave action on the single pile fan were obtained.
