Study on Effect of Step Height and Load for Large Wind Turbine Spreading Foundation

Abstract:

Aiming at the defects and potential safety hazard in design of wind turbine generator foundation, taking the wind power project in Huitengxile as an example and based on ANSYS platform, 3-D numerical model is established by introducing the nonlinear contact between the stub of tower structure and the foundation concrete, and the contact between the concrete foundation and subgrade, the effect of step height and load on the stress status of spreading foundation for large wind turbine are studied. The research results provide reference for optimization and design of wind turbine generator foundation.
