Offshore wind power deepwater pile-anchor flexible composite foundation
The offshore wind power deepwater pile-anchor flexible composite foundation comprises local reinforcing single piles, anchor chains and anti-pulling suction anchors. The local reinforcing single pile can be structurally designed according to the normal operation load of a fan, so that the designed pile diameter is greatly reduced, and the application of the single pile in a deep water area becomes possible; the local reinforcing single pile is connected with the suction anchor through the anchor cable or the anchor chain, and when encountering the short-term limit load effect, the suction anchor can provide large pulling resistance, so that large anti-overturning moment is provided at the height position of the reinforcing ring of the local reinforcing single pile; due to the fact that the anchor cable or the anchor chain is tied to the reinforcing ring of the local reinforcing single pile, pulling resistance provided by the suction anchor generates horizontal component force at the reinforcing ring, the horizontal load generated when the environmental load combination is conducted to the seabed surface is reduced, and the overturning moment generated when the environmental load is downwards transmitted to the seabed surface is reduced; and horizontal displacement is limited when the foundation form is above the sea level, so that the whole fan is easier to be in a safe state under an ultimate load.
本发明公开了一种海上风电深水桩‑锚柔性复合基础，包括局部加强单桩、锚链和抗拔吸力锚；局部加强单桩可按照风机正常运行荷载进行结构设计，从而大大降低了设计桩径，使深水区单桩的应用成为了可能；局部加强单桩与吸力锚通过锚索或锚链进行连接，当遭遇短期极限荷载作用时，吸力锚可提供较大抗拔力，从而在局部加强单桩的加强环高度处提供较大的抗倾覆力矩；由于锚索或锚链系在局部加强单桩的加强环处，吸力锚提供的抗拔力在加强环处产生水平分力，降低了环境荷载组合向海床面传导时的水平荷载，降低了环境荷载向下传递到海床面的倾覆力矩，使该基础形式在海平面以上就限制了水平变位，从而使风机整机在极限荷载下更易处于安全状态。
