Offshore wind power single-barrel composite foundation and construction method thereof
The offshore wind power single-barrel composite foundation comprises a single-barrel foundation and a prestress anchor pulling structure, a bottom plate structure is arranged between a transition section on the upper portion of the single-barrel foundation and a barrel body on the lower portion of the single-barrel foundation, and a bottom plate for separating the transition section and the barrel body is arranged in the bottom plate structure; an embedded hole is formed in the bottom plate in the penetrating direction in a penetrating mode, an anchor pulling auxiliary pipe matched with the embedded hole is arranged in the bottom plate, the bottom end of the anchor pulling auxiliary pipe extends into the barrel body, and an opening is formed in the bottom of the barrel body. The prestress anchor pulling structure is arranged in the anchor pulling auxiliary pipe. The prestress anchor pulling structure is combined with the single-barrel foundation, the load of the upper structure can be effectively transmitted into the deep foundation, the resistance of the lower foundation is effectively utilized, meanwhile, the anchor rod (cable) directly crosses a potential elastic wedge-shaped sliding area soil body on the lower portion of the base of the single-barrel foundation, and the anti-overturning capacity of the single-barrel foundation can be effectively improved.
本发明提供了一种海上风电的单桶复合基础，包括单桶基础与预应力拉锚结构，所述单桶基础在其上部的过渡段与下部的桶体之间设置底板结构，所述底板结构内设置有分隔过渡段与桶体的底板，所述底板内沿沉贯方向贯通开设有预埋孔，底板内设置与预埋孔配合的拉锚辅助管，所述拉锚辅助管的底端延伸至桶体内部，桶体底部设有开口；所述预应力拉锚结构设置在拉锚辅助管内。本发明通过预应力拉锚结构与单桶基础组合，能够有效将上部结构荷载传递至深层地基中，有效利用了下部地基抗力，同时锚杆(索)直接越过单桶基础基底下部潜在的弹性楔形滑动区域土体，能够有效增强单桶基础的抗倾覆能力。
