Method and device for measuring scouring power of offshore wind power single pile foundation and medium

The invention discloses an offshore wind power single pile foundation scouring power measuring method and device and a medium, and aims to solve the problem that the working state of a field fan structure is difficult to reflect because the existing single pile power simulation research after scouring is only used for the power response of part of a wind turbine structure and a standard wind turbine model is used for carrying out numerical simulation research. According to the method, the flexible characteristics of different scouring depths of the pile foundation are considered, the dynamic response of the offshore wind turbine is simulated in the wind-wave-structure-foundation environment by changing the built-in length of the pile foundation, the inherent frequency change of the structure is extracted and analyzed, the actual scouring depth of the wind field is obtained through multi-beam scanning measurement, and the actual scouring depth of the wind field is obtained. And in combination with a dynamic re
