Offshore wind power composite foundation suitable for seabed with sludge covering layer and construction method
The invention discloses an offshore wind power composite foundation suitable for a seabed with a sludge covering layer and a construction method. The offshore wind power composite foundation is a foundation type formed by combining a pile foundation and a gravity type supporting structure, the construction method suitable for the seabed with the sludge covering layer adopts a deep stirring method,sludge around the pile foundation is directly cemented and solidified into a gravity type supporting structure, and the gravity type supporting structure and the pile foundation jointly bear externalloads. The construction method can effectively solve the problems that an existing offshore wind power composite foundation is difficult to be suitable for a seabed with a thick sludge covering layer, and therefore an ultra-large-diameter ultra-long single-pile foundation, a rock-socketed pile foundation, a multi-pile foundation and a jacket foundation have to be adopted, and construction problems caused by the ultra-large-diameter ultra-long single-pile foundation, the rock-socketed pile foundation and the jacket foundation are solved. The construction method is simple, feasible and low in cost, and the pile foundation can be suitable for sea areas with the water depth of 30-60 m and more complex shallow covering layer seabed geological conditions.
本发明公开了一种适用于有淤泥覆盖层海床的海上风电复合基础及施工方法，所述海上风电复合基础是一种桩基础和重力式支撑结构联合形成的基础型式，所述适用于有淤泥覆盖层海床的施工方法是采用深层搅拌法，直接将桩基础周围的淤泥胶结固化成重力式支撑结构，重力式支撑结构与桩基础共同承担外部载荷。本发明的施工方法可以有效解决现有海上风电复合基础很难适用于有较厚淤泥覆盖层的海床，因此不得不采用超大直径超长单桩基础、嵌岩桩基础、多桩基础和导管架基础以及由此带来的施工难题。该施工方法简单可行，成本较低，能够使桩基础适用于水深30~60m海域和更复杂的浅覆盖层海床地质条件。
