Abstract

To quickly calculate the load response of hybrid pile-bucket foundation for offshore wind turbine

based on the PISA （pile soil analysis） monopile design method

the three-dimensional bucket is simplified as a one-dimensional beam attached to the monopile. By adding two soil reaction curves describing bucket-soil interaction to four soil reaction curves describing pile-soil interaction

a one-dimensional （1D） simplified design model of hybrid pile-bucket foundation for offshore wind turbine is established

and the accuracy of the model is verified by comparing it with the existing centrifuge model test results. On this basis

the dynamic response of hybrid pile-bucket foundation under cyclic loads is calculated by applying reduction factors to the soil reaction curves within the bucket depth

and the applicability of this method is discussed. The results show that within the calibration space

the 1D design model has high computational efficiency and accuracy close to the 3D numerical model. Under actual working conditions

the 1D design model can accurately predict the cyclic load response of hybrid pile-bucket foundation. This study can provide theoretical guidance for the design of hybrid pile-bucket foundation for offshore wind turbine.
