Structure types of wind turbine foundation and its calculation methods

As a clean and renewable energy, wind energy is taken more and more attention at the country level around the world. Stable foundations are essential for normal operation of wind turbines. With the wind-power installed capacity increasing, the foundations of wind turbine are extending from onshore to offshore. Thus, the foundations of wind turbine are faced with more complex and severe loading conditions in marine environment. So there would have great theoretical and practical significance to research on the foundations of wind turbine. A current and future state of new development was presented on structure types of wind turbine foundation and its calculation methods at home and abroad in this article. Firstly, there were introduced about the different structure types of wind turbine foundation and its scope of application in onshore and offshore respectively. Then, series of key issues were summarized structural system of wind turbine foundation involving wind turbine loadings, environmental loadings, structural statics, structural dynamics, structural scour, erosion, etc. Finally, some corresponding remaining problems are pointed out from theoretical to practical aspects about wind turbine foundation,some possible directions are put forward and future prospects for researches on wind turbine foundation are explored in China.
