The invention discloses a reinforcing structure for improving the bearing performance of an offshore wind power single-pile foundation under the deepwater condition and an installation method of the reinforcing structure. The single-pile foundation, a floating body structure, an anchoring system and an anchoring pile form a pre-tensioned integral structure, and the floating body structure for improving the horizontal bearing performance is arranged on the single-pile foundation; a plurality of pre-tensioned anchor chains are connected to anchoring piles in a seabed, so that extra horizontal restoring force is provided when the single-pile foundation deforms or inclines, displacement of the wind turbine foundation structure is restrained, horizontal bearing force is increased, the single-pile foundation is made to be suitable for the deeper water depth condition, or the single-pile foundation is used for capacity increasing transformation of a built offshore wind turbine single-pile foundation structure; and the single-pile foundation has the capability of resisting larger marine environment and fan operation load.
本发明公开一种提升深水条件海上风电单桩基础承载性能的加固结构及其安装方法,将单桩基础、浮体结构、锚泊系统、锚固桩形成预张紧的整体结构,其中,在单桩基础上设置提高水平承载性能的浮体结构,并通过若干预张紧的锚链连接至海床内的锚固桩,从而在单桩基础发生变形或倾斜时提供额外的水平回复力,约束风机基础结构位移并增加水平承载力,使单桩基础适用于更深的水深条件,或用于已建海上风机单桩基础结构的增容改造,使单桩基础具备抵抗更大的海洋环境以及风机运行荷载的能力。
