The beam-slab type foundation is a new type of Wind Turbine Generators Tower Foundation. It has advantages over traditional foundation in being more convenience and reasonable. Here the finite element analysis software ANSYS is being used to get the reasonable disposal of the s beam-slab type foundation and analyze the static characteristics of the new structure such as stress, displacement and settlement of foundation. The FEM model is created according to the factual three-dimensional mode. The calculation and analysis results are useful in the optimum design of the structure.
