风能作为一种绿色环保的可再生能源具有重要的应用前景,海上风力发电的研究受到广泛关注。在波浪和潮流荷载作用下,会导致风电桩基周围土体发生局部冲刷,影响桩基的性能。阐述了海上风电单桩基础局部冲刷的研究进展,综述了桩基局部冲刷的机理,总结了不同的平衡冲刷深度计算方法,对不同学者的模型试验、数值计算以及现场观测进行对比分析,探讨其中的不足并提出若干展望和思考。相关研究成果显示结合现场观测数据和冲刷预测模型的海上风机单桩基础防冲刷设计是有效的。
Abstract：As a kind of green and renewable energy, wind energy is gradually replacing fossil energy, and the study on offshore wind power generation has been received extensive attention. The local scour around monopile will be caused by wave and tidal current, which will affect the performance of the pile foundation. The paper illustrates the study progress of local scour around the monopile of offshore wind turbine with detailed summary of the mechanism of local scour around pile, the different equilibrium scour depth calculation method, and different model test. Numerical calculation and on-site observation are carried on the contrast analysis to explore the problems and prospects. Study results show that design based on both observation data and the pile foundation scour prediction of monopile foundation for offshore wind turbines anti-scour is effective.
