Study on the Influence of Pile Foundations of Large-Scale Offshore Wind Farm on Marine Hydrodynamic Environment
Based on the Qingzhou Offshore Wind Farm Project in Yangjiang,Guangdong Province,this study uses MIKE21 software to build a two-dimensional hydrodynamics mathematical model,combines the measured tide and flow data of the project area to calibrate and verify the model,and analyzes the changes of the flow before and after the construction of large-scale offshore wind power projects.The results show that after the construction of the wind farm,the backwater surface of a single pile foundation is the flow velocity reduction area,and the flow velocity increase area perpendicular to the fluctuation and tidal flow direction is the flow velocity increase area.Considering the layout of 7 wind farms comprehensively,the wind turbine base group has a velocity decrea-sing area in the direction of water facing and back,and a velocity increasing area in the direction of ebb and flow perpendicular to the wind farm.The range of tidal flow velocity changing direction is mainly confiined to the con-tinual area of 7 wind farms,and the superposition effect of the seven wind farms is not obvious.
