Abstract:Based on the anchor bolt foundation of the wind turbine generators(WTGS) of Goldwind with 100m high hub, the mechanical characteristics of the beam-plate typed prefabricated foundation of the WTGS were studied. Through the ANSYS modeling, the stress conditions of the prefabricated anchor bolt foundation of WTGS were analyzed including the main structure concrete of foundation, high strength grouting material, upper and lower anchor plates and the prestressed anchor bolts. The research shows that the maximum concrete shrinkage deformation is about 0-003m, so the prefabricated WTGS foundation is in small deformation range; the maximum horizontal compressive stress is 27-1MPa and the maximum horizontal tensile stress is 3-44MPa for the local parts of the main structure concrete of the foundation, and the stresses exceed the design value of the C40 concrete strength, so the local concrete reinforcement should be strengthened; the maximum tensile stress of the prestressed anchor bolt is 424MPa, less than the yield strength of the 8-8 degree anchor bolt, and the structure of the anchor bolt is safe. The results can provide reference for the design and calculation of prefabricated WTGS foundation.

Keywords:prefabricated structure; foundation of wind turbine generators(WTGS); prestressed anchor bolt; anchor plate; ribbed beam
