The invention belongs to the technical field of ocean piled anchors, and provides a novel ocean gravity piled anchor used for resisting uplift loads and an installation method thereof.The gravity piled anchor comprises a piled anchor body, the top of the piled anchor body is vertically downwards provided with a containing space, and the bottom of the piled anchor body is conical; according to the invention, sinking penetration can be carried out by adopting a piling mode, and ballast penetration can be carried out by virtue of an offshore self-elevating platform; and after penetration in place, the accommodating space is filled with iron ore sand or concrete. Aiming at long-term continuous cyclic dynamic load generated by the floating platform, the floating platform has high in-place bearing efficiency, low sensitivity to seabed scouring, high applicability to engineering geological conditions of a site, low mounting noise and high environmental friendliness when ballast injection is adopted, so that cost reduction and efficiency improvement of floating wind power are realized, and the floating platform is suitable for large-scale popularization and application. And particularly, the industrial development of tension leg type floating wind power can be obviously promoted.
本发明属于海洋桩锚技术领域，提供了一种用于抵抗上拔荷载的海洋新型重力桩锚及其安装方法，此重力桩锚包括桩锚，所述桩锚顶部竖直向下开设有容纳空间，所述桩锚底部为锥形；本发明针既可采用打桩的方式进行沉贯，也可借助海上自升式平台进行压载贯入；沉贯就位后，其容纳空间采用铁矿砂或混凝土进行填充。本发明针对漂浮式平台产生的长期持续的循环动荷载，有较高的在位承载效率，对海底冲刷的敏感性低，对场地的工程地质条件适用性强，采用压载贯入时，安装噪音小，环境友好性高，因此对于漂浮式风电的降本增效，特别是张力腿式漂浮式风电的产业化发展，有显著的促进作用。
