In the continuous implementation of wind power projects,for the construction of wind turbine foundation projects,the concrete at the bottom of the foundation is subject to significant bearing stress,which can easily lead to concrete cracking under different working conditions.New technologies need to be applied to improve the crack resistance of the bottom concrete.From the perspective of the construction industry,prestressing technology can improve the crack resistance of structures.Therefore,this paper studied the scheme of applying prestress on the foundation base plate,explored and analyzed the reinforcement and effect verification when using and not using prestressed reinforcement,and finally conducted simulation and experimental discussion.Applying prestress on the base plate can reduce the maximum crack width,enhance the stability of the wind turbine foundation base plate,and improve power generation efficiency.
