[0002] The structure of wind power generation (abbreviated as wind power) can be mainly divided into several major components according to its functions, such as blades, the nacelle, the tower barrel, and the foundation. Among them, the foundation part undertakes the function of transferring the loads received by the upper structure (blades, the nacelle, the tower barrel) to the ground, and it accounts for about 20%-30% of the total cost of the entire wind power generation structure.
