Review on Static Mechanism of Grouted Connection in Offshore Wind Farm

Grouted connection of offshore wind turbine foundation is a key point in the design and construction process. The connection is affected by axial force, bending and coupling during the long-term operation of wind turbine. In this paper, the static mechanism of grouted connection is mainly studied from the aspects of axial compression and bending moment. Firstly, the axial compression mechanism of grouted connection with/without shear keys is described in detail, and then bending mechanism of the grouted connection is expounded. Finally, the static mechanism research of grouted connection is summarized.
