The invention belongs to the technical field of ocean engineering, and provides a variable-cross-section three-stand-column type offshore floating wind power foundation which comprises a bottom structure, a center stand column arranged on the bottom structure and a plurality of circumferential stand columns arranged on the bottom structure around the center stand column. Contact sections intersecting with the water surface are arranged on the circumferential stand columns, the sectional area of the middle of each contact section is smaller than the sectional areas of the tail ends of the two ends of the contact section in the axial direction of the circumferential stand columns, and the sectional areas of the contact sections are gradually increased from the middle to the tail ends of the two ends. According to the floating type wind power foundation, the wave load and dynamic response of waves to the floating wind power foundation can be effectively reduced, and the seakeeping and power generation benefits of floating wind power are improved.

    本发明属于海洋工程技术领域,提供一种变截面三立柱式海上浮式风电基础,包括底部结构、设置在所述底部结构上的中心立柱,以及环绕所述中心立柱设置在所述底部结构上的若干周向立柱;若干所述周向立柱上均设置有与水面交汇的接触段,沿所述周向立柱的轴向,所述接触段的中部的截面积小于所述接触段两端末端处的截面积,且所述接触段的截面积由中部朝向两端末端处逐渐变大。本发明可以有效减小波浪对浮式风电基础的波浪荷载和动力响应,提高浮式风电的耐波性和发电效益。
