摘　　要：单桩基础的冲刷及冲刷防护方案的选择,对海上风电场安全稳定运行和降低运维成本具有重要意义。分析单桩基础冲刷机理及实际工程案例,介绍目前国内外常见的冲刷防护方案,提出基于人工礁技术的海上风电单桩基础冲刷防护方案。首先介绍人工礁单个模块的基础结构,并结合单桩基础冲刷模型,提出人工礁链接技术。针对风机所处的海洋水文和地质情况,对人工礁连锁块的结构形状进行优化比较。海上风电项目试验桩位的扫测结果表明人工礁冲刷方案防护效果良好,基于人工礁的单桩基础冲刷防护方案在海上风电基础的防冲刷应用具有较好的推广意义。The scouring of monopile foundation and the choice of erosion protection scheme are of great significance to the safe and stable operation of offshore wind farms and the reduction of operation and maintenance costs.The erosion mechanism and actual engineering cases of monopile foundation are analyzed,the common erosion protection schemes at home and abroad are introduced,and the erosion protection scheme of offshore wind power monopile foundation based on artificial reef technology is proposed.Firstly,the basic structure of a single module of artificial reef is introduced,and combined with the monopile foundation erosion model,the artificial reef linking technology is proposed.Then,according to the marine hydrological and geological conditions where the wind turbine is located,the structural shape of the artificial reef interlocking block is optimized and compared.The scanning results of the test pile of the offshore wind power project show that the artificial reef erosion scheme has a good protection effect.The monopile foundation erosion protection scheme based on artificial reef has good promotion significance in the application of anti-erosion of offshore wind power foundation.
