Abstract:

A new type of prefabricated foundation for onshore wind power was proposed in this paper. The stress and bearing mechanism of the new foundation was explored through theoretical calculation and finite element analysis. The results show that compared with the extended foundation in the same position, the amount of concrete in the new foundation is reduced by 30.00%, and the amount of rebars are reduced by 34.69%. The new prefabricated foundation has been inspected and calculated according to the specification. The calculation results indicate that the stress and initial reinforcement of the foundation meet the specification requirements. The bearing capacity, inclination rate, deformation, and stability of the foundation meet the requirements. Through finite element analysis, it is further confirmed that the structure meets the requirements of wind turbine operation, and the overall force meets the requirements of various indicators. The stress distribution of the foundation concrete and rebars is reasonable and uniform, and the load transfer is great. Also, the maximum stress of rebars and concrete does not exceed the specification limit, and the concrete remains intact without cracking or damage. The new foundation structural design and theoretical analysis were reasonable and accurate, and can be put into application in the future.
