Offshore wind power foundation with anti-scouring function
The invention provides an offshore wind power foundation with an anti-scouring function. The offshore wind power foundation comprises a pile foundation and a stop strip. The stop strip is arranged on the pile foundation, a groove which is sunken downwards is formed in the upper surface of the stop strip, the groove can actively disturb down flow flowing downwards along the pile foundation, the effect of stopping the down flow is achieved, the flow speed and the direction of the down flow are changed, the effects of energy dissipation and impact reduction are achieved, and formation of horseshoe-shaped vortexes is restrained. The soil body around the pile foundation is effectively protected, and the formation of a scour pit is avoided. Compared with a riprap protection method in the related technology, the stability is higher, the anti-scouring effect is better, and the reliability is better.
本发明提出了一种具有防冲刷功能的海上风电基础，包括桩基础和止挡条。桩基础上设置止挡条，止挡条的上表面设置有向下凹陷的凹槽，凹槽能够对沿着桩基础向下流动的下降流进行主动扰流，起到阻挡下降流的作用，改变下降流的流速和方向，起到了消能减冲的效果，抑制了马蹄型漩涡的形成，有效地保护桩基础周围的土体，避免冲刷坑的形成。与相关技术的抛石防护法相比，稳定性更强，防冲刷效果更好，可靠性更好。
