[0002] With the continuous development and utilization of new energy, different types of new energy have been gradually widely used in various power systems. As one of the important new energy sources, the application and development of offshore wind power has gradually become popular. As an important carrier for the development of offshore wind power, the stability and reliability of the structure of offshore wind turbines are of great significance for the development of new energy sources of offshore wind power.

[0003] Due to the particularity and complexity of the working environment of offshore wind turbines in the marine environment, a large number of calculations need to be performed in the design environment of offshore wind turbines to determine the foundation structure of the offshore wind turbine's jacket and monopile. However, in the current foundation structure process of the jacket and monopile of offshore wind turbines, the jacket and monopile are usually designed and verified independently, and then the offshore wind turbine is constructed. This method pays too much attention to the independent design concept between the jacket and the monopile, resulting in low construction efficiency of the offshore wind turbine; in addition, due to the independent design, the jacket and the monopile have certain defects in compatibility, and continuous adjustments are required to construct the offshore wind turbine, which also leads to low construction efficiency of the offshore wind turbine. Therefore, there is an urgent need for a simulation method and device for the foundation structure of the jacket and monopile of an offshore wind turbine to solve the defects of the existing technology.
