@@@@?Based on the sole-plate’s form of turbine-generator unit foundation, a variety of turbine foundation has been researched with three-dimensional solid finite element. The spring element are employed to imitate the ground soil, the effect of sole-plate’s form and thickness are considered,and the turbine, basic structure and foundation soil are cooperation. Dynamic analysis of harmonic response for turbine-generator foundation is studied. The displacement amplitude of turbine foundation was got, the dynamic response of all kinds of foundation are discussed. References for the design of similar projects are provided.
