Concrete filled steel tube pile-composite structure bearing platform foundation with damping device
The invention discloses a concrete filled steel tube pile-composite structure bearing platform foundation with a damping device, and belongs to the technical field of offshore wind power generation. The upper portion of the bearing platform foundation is a combined structure bearing platform, the lower portion of the bearing platform foundation is a steel pipe concrete pile, and a damping device is arranged in the combined structure bearing platform. In the combined structure bearing platform, a steel plate framework formed by welding a plurality of steel plates is used for replacing dense reinforcement cages in a traditional bearing platform, and concrete is filled in the combined structure bearing platform. The steel pipe concrete pile head welding studs are embedded into the combined structure bearing platform and are connected with the steel plate framework; the damping device is filled with viscous liquid, and the damping and energy dissipation effects are achieved through vibration of the sliding block and the eight springs. The advantages of a combined structure are fully exerted, the stress form is reasonable, joint connection is reliable, the horizontal earthquake effect in any direction can be resisted, the structural bearing capacity is high, and durability is high.
本发明公开了一种具有减震装置的钢管混凝土桩‑组合结构承台基础，属于海上风力发电技术领域。该承台基础上部为组合结构承台、下部为钢管混凝土桩、组合结构承台内部配有减震装置。所述组合结构承台内部以多块钢板焊接而成的钢板骨架代替传统承台内部密集的钢筋笼，组合结构承台内部填充混凝土；所述钢管混凝土桩头焊接栓钉嵌入组合结构承台内部并与钢板骨架相连；所述减震装置内部填充粘滞液，通过滑块和八个弹簧的振动发挥减震耗能作用。本发明充分发挥了组合结构的优势，受力形式合理，节点连接可靠，能够抵抗任意方向的水平地震作用，结构承载力高，耐久性强。
