Abstract: As the part of offshore platform, the suctional bucket foundation bears not only the vertical loading induced by the weight of offshore platform structure and itself but also torsion shear loadsing induced by wave and wind. However, there is no a commonly\|acceptable calculation mode and analytical method for the torsional shear of suctional bucket foundation. According to the transversely anisotropy of soft clay, the bearing performance of bucket foundation is studied under the condition of tortional shear loading by FEM, in which a series of changing parameters are compared calculation, then the amount of calculated results is analyzed systematically, their numerical calculation results and analysis are provided as the reference for engineering design.
