Single-pile foundation of composite column pile foundation of offshore wind turbine generator and construction method of single-pile foundation
The invention discloses an offshore wind turbine generator composite column pile foundation single-pile foundation and a construction method thereof. The foundation comprises a connecting flange, a first straight-section single-pile structure, a reducing-section single-pile structure, a second straight-section single-pile structure, a composite column single-pile structure and a third straight-section single-pile structure which are sequentially connected along the same central axis from top to bottom. Wherein the first straight-section single-pile structure is arranged on the sea level, the second straight-section single-pile structure is arranged on the seabed mud surface, and the diameter of the first straight-section single-pile structure is smaller than that of the second straight-section single-pile structure; the horizontal, vertical and anti-bending bearing capacity is enhanced while the weight of a single pile foundation is not increased, the overall structural rigidity of a pile body is improved, the diameter of the foundation on the water surface is reduced, the wave acting force near the water surface is reduced, the control effect on horizontal displacement is enhanced, and the bearing performance of the foundation is improved; and meanwhile, the single-pile foundation effectively solves the problem of construction and installation of a super-large-diameter single pile, and has better economic benefits and application prospects.
本发明公开了一种海上风电机组复合柱桩基单桩基础及其施工方法，该基础包括从顶部到底部沿同一中心轴依次连接的连接法兰、第一直段单桩结构、变径段单桩结构、第二直段单桩结构、复合柱单桩结构以及第三直段单桩结构；其中，所述第一直段单桩结构设置于海平面处，所述第二直段单桩结构设置于海底泥面处，所述第一直段单桩结构的直径小于第二直段单桩结构的直径；本发明在不增加单桩基础重量的同时增强水平、竖向及抗弯承载力，提高桩体整体结构刚度，降低水面处基础直径，减小水面附近处的波浪作用力，增强对水平位移的控制作用，提高了基础的承载性能，同时该单桩基础有效地解决了超大直径单桩施工安装的难题，具有更好的经济效益和应用前景。
