摘要：
Taking NREL 5 MW monopile offshore wind turbine as a model, the finite element model is established based on p-y curve method and soil damping curve. The structural response of offshore wind turbine based on soil damping curve is respectively obtained through free vibration analysis and time domain simulation analysis. The results show that the soil damping of supporting structure is sensitive to soil shear strain, the free vibration analysis results reach the maximum value 1.259% under rated conditions. Compared with the top displacement and tilt of tower, the maximums at the mudline are more sensitive to soil damping. In the design process, the soil damping curve can be selected for soil modeling considering the soil material damping. © 2019, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
