3D FEM analysis on bearing capacity behaviors of tri-piles foundation for offshore wind turbines

With the development of wind power generation technology, offshore wind power generation plays a major role for developing renewable sources in the world today. According to the proposed Hangzhou Bay wind farm, based on general-purpose finite element software, bearing capacity of the jacket foundation for offshore wind turbine has been simulated by the three dimensional finite element numerical method. The Mohr Coulomb model has been adopted as the elastic plastic constitutive models of the soil and the Coulomb Friction model for the pile soil contact model Using the established finite element model, the bearing capacity behavior of multi-pile foundation for offshore wind turbines under monotonic and combined loading are studied, and the bearing capacity behavior of multi-pile foundation for offshore wind turbines by changing diameter, distance of piles and loading directions are elaborated.
