| 摘 要： | 以福建某海滩单机容量为2.5MW海上风力发电机为原型,应用ABAQUS有限元软件分别建立风力发电塔的地基刚接模型和考虑土与结构相互作用的质量-弹簧-阻尼模型.通过给模型施加地震波,对风力发电塔体系进行地震动力作用时程分析.主要研究了土与结构相互作用（Soil-structure interaction,SSI）对风力发电塔体系地震响应的影响.研究表明,SSI效应降低了风力发电塔的地震应力响应,增加了其地震位移响应.

| Abstract: | Taking an offshore wind turbine in Fujian which unit capacity is 2. 5MW as the proto- type, this paper mainly focus on the impact on the dynamic response of a wind turbine system under earthquake action with the consideration of soil-structure interaction. Based on finite element software ABAQUS, the rigid base model and the mass-spring-damper model taking the soil-structure interaction in- to consideration are built respectively. Then, the time history analysis of the system under the action of seismic waves is carried out. The results show that SSI effect is significant for seismic response of a wind turbine system. |
