The multi-layer foundation construction method for the wind turbine generator is characterized in that according to the requirement for iterative updating of the wind turbine generator, multiple layers of foundation structures are sequentially constructed on the site selection of the wind turbine generator from inside to outside, the inner-layer foundation structure is used for bearing the current-generation wind turbine generator, and the outer-layer foundation structure is used for bearing the replaced new wind turbine generator. And at least one outer-layer foundation structure is constructed. According to the method, it is avoided that when the wind turbine generator needs to be iteratively updated, the foundation of the wind turbine generator is dismantled, and foundation excavation and pouring are conducted again, the foundation construction period of updating and replacing of the wind turbine generator is shortened, and the outer-layer foundation structure is prefabricated for updating and replacing of
