The utility model has the beneficial effects that:
1) the application range of this structure is wide, except not requiring the ground, can also be used for on pile foundation and the stock basis, the outward flange in the basis bottom sets up round annular polystyrene board, it bears the soil weight on upper portion to establish reinforced concrete board on the polystyrene board, the interior basic concrete of polystyrene board is direct and the contact of ground bearing layer, make the ground bearing capacity of this area scope, deformation and stability satisfy standard requirement, utilize the increase of soil body weight, under the condition of increasing few basic concrete, the counter weight on greatly increased basis, reach the requirement that the basis satisfies the area of allowing to break off.
2) The design has simple structure, definite force transmission and convenient manufacture. The structure greatly saves the consumption of reinforced concrete and reduces the manufacturing cost. The structure has no requirement on the foundation, and the foundation meeting the bearing capacity requirement can be used.
3) The thickness and the reinforcing bars of the reinforced concrete slab on the polystyrene slab are determined according to design calculation.
4) In the research, the foundation concrete on the inner side of the polystyrene plate is directly contacted with the foundation bearing layer, so that the bearing capacity, deformation and stability of the foundation in the area range meet the standard requirements, and the soil borne by the reinforced concrete plate on the polystyrene plate is used for increasing the balance weight of the foundation to resist the unfavorable bending moment of the wind turbine generator, so that the foundation meets the requirement of the allowable disengagement area.
5) The fan foundation directly contacts with the foundation bearing layer, so that the bearing capacity, deformation and stability of the foundation in the area range meet the standard requirements.
6) The polystyrene board can be used as a template of a fan foundation.
