Offshore wind power foundation structure with anti-overturning function

The invention relates to the technical field of offshore wind power foundations, in particular to an offshore wind power foundation structure with an anti-overturning function, which comprises a vertically arranged truss structure, a suction barrel with a downward opening arranged at the lower end of the truss structure, and a transition section arranged at the upper end of the truss structure and used for connecting a wind turbine generator, and is characterized by further comprising a pile rod, the pile rod is vertically arranged in the truss structure, the upper portion of the pile rod is connected with the truss structure, and the lower end of the pile rod is arranged below the suction barrel. By arranging the pile rod, the pile rod can be inserted into subsea soil in a deep pile driving mode, lateral supporting force is provided by means of the pile rod, and the situation that the center of the whole foundation structure deviates and overturns due to the fact that the suction barrel inclines towards a ce
