Offshore wind power polygonal cylindrical foundation
The invention relates to an offshore wind power polygonal cylindrical foundation. The foundation comprises a transition section, a polygonal bottom plate, a bottom plate beam system and a polygonal cylinder. The foundation is suitable for ocean geological conditions with thick soft clay layers, has the advantages of large bearing area, capability of sinking under negative pressure, capability of being mounted in one step, good stability in place and the like of a traditional cylindrical foundation, and has the unique advantages that the cylinder wall and an outer bin plate cannot be bent, thespan of the bottom plate is reduced, formwork erecting is convenient, the floating transportation gravity center of the foundation is low, the stability is good, the jig frame cost is saved, formworkmanufacturing is convenient, and the repeated utilization rate is high; and the foundation sinking construction stability is improved, compared with a conventional composite cylindrical foundation onthe same site, the comprehensive manufacturing cost can be reduced by 10%-25%, a certain angle is formed between the corresponding directions of a polygonal inner bin dividing plate and a polygonal cylinder wall, the problem that a connecting joint of the cylinder wall and an outer bin plate of an original polygonal cylindrical foundation is prone to damage due to large stress is solved, the length of the outer bin plate is greatly reduced, and the problem that the outer bin plate is prone to buckling during inflation sinking is solved.
本发明涉及一种海上风电多边形筒型基础，包括过渡段、多边形底板、底板梁系和多边形筒，适用于软弱黏土层较厚的海洋地质条件，不仅兼有承载面积大、可负压下沉、可一步式安装以及在位时稳定性佳等传统筒型基础的优点，且独有筒壁和外仓板不会屈曲、减小底板跨度方便支模、基础浮运重心低、稳性佳、省去胎架费用、模板制作方便、重复利用率高等优势，提高了基础下沉施工的稳定性，相比于同一场地的常规复合筒型基础可减少综合造价10％～25％，多边形内分仓板与多边形筒壁对应方向相差一定角度，解决了原有多边形筒型基础的筒壁与外仓板连接节点受力大易产生破坏问题，大大缩小了外仓板长度，减小外仓板充气下沉时易屈曲问题。
