The invention relates to a steel cylinder type foundation structure of an offshore wind turbine. The steel cylinder type foundation structure is characterized by comprising an upper steel cylinder, a steel cover plate, a lower steel cylinder and shifting boards, wherein the upper steel cylinder is fixedly connected with the steel cover plate; the steel cover plate is fixedly connected with the lower steel cylinder, an inner steel cylinder is arranged in the lower steel cylinder, a plurality of steel compartment are formed between the lower steel cylinder and the inner steel cylinder by division of the shifting boards, and reserved holes are formed in the steel cover plate. The steel cylinder type foundation structure disclosed by the invention has the beneficial effects that compared with the prior art, complete onshore control can be realized, the offshore operation time of a foundation of the offshore wind turbine is reduced, the advantage of a caisson cylinder structure which is suitable for a soft foundation without foundation reinforcement treatment and the construction technology of the caisson cylinder structure which sinks by negative pressure after being vacuumed are fully utilized, the defects that a concrete structure is easy to crack and is poor in durability are overcome, and the whole rigidity and the stability of the structure are increased.read more
