Abstract: For the serious problem of pile foundation erosion in the operation of the single pile foundation of the second phase of the Wailuo Wind Farm， the analysis and research on the causes of pile foundation erosion in the industry are studied， and the principle of single pile foundation erosion is analyzed in combination with the characteristics of the sea conditions in the region. The target position is selected according to the three-dimensional scanning results， and a treatment scheme for the active anti-scouring of honeycomb turbulence is proposed for the target position based on the previous treatment experiences. The technical principles and basic scheme are studied， the basic structural design of the device is completed， and then the project demonstration is implemented. Through the prototype test， it is proved that the honeycomb turbulence active antiscouring device has good feasibility in the anti-scouring protection of offshore wind power single pile foundation， and has certain application reference and promotion value.

Key words: single pile foundation, cellular spoiler, active anti-scouring
