基于外罗二期风电场单桩基础运行出现严重桩基冲刷问题，借鉴行业内对桩基冲刷产生原因的分析研究，结合本区域海况特点对单桩基础冲刷原理进行分析。依据三维扫测结果选择目标机位，在以往治理经验的基础上对目标机位提出一种蜂窝扰流主动防冲刷的治理方案并进行技术原理、基本方案研究，完成装置的基本结构设计，之后进行工程示范实施。通过样机试验，证实蜂窝扰流主动防冲刷装置在海上风电单桩基础的防冲刷保护方面具有较好的可行性，有一定的应用和推广价值。

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.
