The invention provides a combined type offshore wind power foundation structure. The combined type offshore wind power foundation structure comprises a cylindrical foundation, transition connecting pieces and a plurality of auxiliary piles. The cylindrical foundation comprises a cylindrical upper cover and a cylindrical wall; a plurality of partition plates are arranged in the cylindrical foundation, and all the partition plates divide the interior of the cylindrical foundation into a plurality of partition cabins of the same structure. Vertically arranged bearing cylinders are arranged in at least two of all the separated cabins, each bearing cylinder is provided with a hollow channel, a plurality of cover plate through holes are formed in the top surface of the cylinder body upper cover, the cover plate through holes are communicated with the corresponding hollow channels, and the diameter of the cover plate through holes is equal to that of the hollow channels; a plurality of water pumping ports are formed in the barrel upper cover, and each water pumping port is communicated with one partition cabin; auxiliary piles are inserted into the hollow channels and connected with the hollow channels. According to the combined offshore wind power foundation structure, the overall bearing capacity of the soil body and the cylindrical foundation is improved.

本发明提供一种组合式海上风电基础结构，包括：筒形基础、过渡连接件和多个辅助桩；筒形基础包括筒体上盖和筒壁；筒形基础的内部设有多个分隔板，所有的分隔板将所述筒形基础的内部分隔为多个结构相同的分隔舱；所有的所述分隔舱中的至少两个所述分隔舱中设有竖直设置的承接筒，每个承接筒上具有中空通道，筒体上盖的顶面上设有多个盖板通孔，所述盖板通孔与相应的所述中空通道连通，所述盖板通孔的直径与所述中空通道的直径相等；筒体上盖上设有多个抽水口，每个抽水口与一个所述分隔舱连通；中空通道供辅助桩插入，辅助桩与中空通道连接。该组合式海上风电基础结构增加了土体与筒形基础的整体承载力。
