| Abstract: | Based on the feature that offshore wind turbine tower supporting structures are affected by soil foundation and the ocean flow,the paper establishes 3D finite element numerical model to get dynamic characteristics of supporting system structure of different scour depths and discusses its change law in order to provide scientific basis for dynamic stability design of offshore wind turbine tower supporting structure. |
