    • Abstract
  • The composite bucket foundation is a new type of wind power infrastructure, and its stability needs to be further verified. The in-situ monitoring of the construction project of Dafeng Offshore Wind Power Plant by China Three Gorges Corporation is carried out. Based on the multi-directional inclination automatic monitoring system and numerical simulation, the variation rules of the inclination and attitude of the structures in the process of installation and operation are studied. The results show that the composite bucket foundation under compound loads and fan operation is stable, and the largest inclination meets the condition of the stability of less than 0.5 °. The amplitude and frequency of angle fluctuation are relatively large during sinking installation, which is the key stage of stability monitoring and control. With the completion of installation, the attitude of wind turbine gradually tends to be stable, and slowly evolves under the action of wind, waves and currents. The evolution path laws can reflect the mechanical response characteristics of the composite bucket foundation.
