为研究DTU 10MW近海桩柱式风力机塔架在地震激励下的动力学响应，基于p-y曲线法建立单桩基础与土壤的耦合模型，通过有限元软件ANSYS建立风力机塔架的有限元模型，分析不同速度湍流风和不同强度地震时塔架的瞬态动力学响应。结果表明：仅风载荷作用时，额定风速作用下塔架动力学响应明显高于切出风速；地震与风联合作用时，塔顶位移动态响应剧烈，但无明显规律；塔架加速度响应最大值位置约为四分之三塔高处，塔顶剪应力响应与地震持续时间有关。

In order to study the dynamic response of DTU 10MW offshore monopiles wind turbine tower under seismic,the coupling model between pile and soil was established based on p-y curve,and the wind turbine tower′s finite element model was established by finite element software ANSYS to analyze transient dynamic response of the tower during different speed turbulent wind and different intensity seismic.The results show that the tower dynamic response is significantly higher than the cutout wind speed under the rated wind speed when only the turbulent wind is applied.When the seismic and the turbulent wind act together,the dynamic response of the top displacement is severe,but there is no clear law.The maximum position of the tower acceleration response is about threequarters of the tower height,and the shear stress response at the top of the tower is related to the duration of the seismic.
