Pre-tensioning pile-anchor combined foundation for shallow covering layer seabed and construction method of pre-tensioning pile-anchor combined foundation
The invention discloses a pre-tensioning pile-anchor combined foundation for a shallow covering layer seabed and a construction method of the pre-tensioning pile-anchor combined foundation. The pre-tensioning pile-anchor combined foundation comprises a fan, a tower drum and a pile foundation which are sequentially connected from top to bottom, and the bottom of the pile foundation is vertically embedded into a soft soil layer and makes contact with a rock layer; a plurality of anchor rods are fixedly connected to the side wall of the pile foundation at intervals in the annular direction through connecting devices, and the other end of each anchor rod penetrates through the soft soil layer, is embedded into the rock layer and is fixedly connected with the rock-socketed anchoring end. The vertical force borne by the pile foundation is mainly borne by the friction force of the surface soil and the rock-soil layer at the pile bottom, the horizontal load is borne by the soil body around the pile, the anchor rods and the rock-socketed anchoring ends of the anchor rods, the bearing capacity is stable, construction and installation are convenient, the rigidity is large, and good stability of the upper structure of the offshore wind turbine is guaranteed.
本发明公开了一种用于浅覆盖层海床的预张桩锚组合基础及其施工方法，包括由上至下依次连接的风机、塔筒与桩基础，所述桩基础底部垂直嵌入软土层内并与岩石层接触；所述桩基础侧壁通过连接装置环向间隔固定连接有若干锚杆，且每个锚杆的另一端穿过软土层并嵌入岩石层内与嵌岩锚固端固定连接。本发明中，桩基础承受的竖向力主要由表层土的摩擦力和桩底的岩土层承担，水平荷载则通过桩周土体、锚杆及其嵌岩锚固端来承担，承载能力稳定，便于施工和安装，且具有较大的刚度，保证了海上风机上部结构良好的稳定性。
