Novel offshore wind power single-pile composite winged cylindrical foundation and construction method thereof
The invention discloses a novel offshore wind power single-pile composite winged cylindrical foundation and a construction method thereof. The cylindrical foundation comprises a cylindrical foundation body with wing plates and a single pile; the single pile and the cylindrical foundation body with the wing plates are connected through a high-strength concrete grouting material, so that the resistance of shallow soil of a seabed can be brought into full play, and the capability of integrally resisting transverse loads, bending moment, overturning loads and torque generated by non-coplanar load of a wind power foundation is enhanced. The wing plates and a cylinder body can effectively reduce the displacement of a pile body on a mud surface, so that the purpose of reducing the diameter and the thickness of the pile is achieved, and the pile driving cost for the large-diameter single pile is reduced while the overall stability of the foundation is enhanced. Vertical loads are mainly borne by the single pile, and the cylindrical foundation with the wing plates can bear part of the load; and the transverse loads and bending moment loads generated by wind waves, waves and the like are mainly borne by the cylindrical foundation body with the wing plates, and the single pile also plays a certain role.
本发明公开了一种海上风电单桩复合带翼新型筒形基础及其施工方法，该筒形基础包括带有翼板的筒型基础和单桩，本发明通过高强混凝土灌浆材料将单桩和带有翼板的筒型基础连接，能够充分发挥海床浅层土的抗力，增强风电基础整体抵抗横向荷载、弯矩和倾覆荷载及由非共面荷载产生的扭矩的能力。翼板和筒体能够有效减小泥面处的桩身位移，从而达到减小桩的直径和厚度的目的，进而在增强基础整体稳定性的同时减少了针对大直径单桩的打桩成本。竖向荷载主要由单桩承担，带有翼板的筒型基础能够分担部分荷载；风浪流等产生的水平荷载和弯矩荷载主要由带有翼板的筒型基础承担，单桩也起到了一定的作用。
