Design and construction method of concrete-filled steel tube mixing composite pile foundation for offshore wind power
The invention relates to a design and construction method of a concrete-filled steel tube mixing composite pile foundation for offshore wind power, which comprises the following steps of: selecting a support body matched with offshore wind power equipment according to the load requirement of the offshore wind power equipment and the depth of seawater, and adopting one of a bearing platform or a multi-foot stand; according to the condition that a bearing platform is adopted as a supporting body, a plurality of concrete-filled steel tube mixing composite piles are constructed below the bearing platform, and the concrete-filled steel tube mixing composite piles are obliquely arranged below the bearing platform at a certain angle and form an outward oblique scattering shape; aiming at the condition that a multi-foot stand is adopted as a supporting body, a plurality of concrete-filled steel tube mixing composite piles are constructed below the bearing platform, and the plurality of concrete-filled steel tube mixing composite piles are vertically arranged below the multi-foot stand. The method has the advantages that the structure stress is reasonable, the foundation cost and the construction difficulty are reduced, the corrosion resistance of the foundation is improved, the good anti-fatigue performance is achieved, and the service life of the foundation is prolonged.
本发明涉及一种海上风电用钢管混凝土搅拌复合桩基础的设计施工方法，根据海上风电设备的荷载要求以及海水的深度，选择与海上风电设备所适配的支撑体，其采用承台或多脚架中的一种；针对采用承台作为支撑体的情况，在承台的下方施工若干钢管混凝土搅拌复合桩，若干钢管混凝土搅拌复合桩分别呈一定角度的倾斜布置在承台下方并形成向外的倾斜散射状；针对采用多脚架作为支撑体的情况，在承台的下方施工若干钢管混凝土搅拌复合桩，若干钢管混凝土搅拌复合桩呈竖直布置在多脚架的下方。本发明的优点是：1）结构受力合理，降低基础成本及施工难度；2）提高基础抗腐蚀性；3）具有良好的抗疲劳性能；4）提高基础使用寿命。
