Abstract

The single pile foundation of offshore wind turbine is currently the most common form, but the huge loads and the overturning moment make characteristics of foundation is different from offshore oil platforms. Using elastic-plastic element of ABAQUS simulation of pile foundation in bearing stress and failure modes in different soil layers. The results show that the single pile foundation subjected to vertical ultimate load in different soil layers, no plastic strain. Under the horizontal ultimate load, pile shows plastic strain. Under limit bending moment load, the plastic zone in the soil is mainly distributed in the surface soil in front of pile. Use ABAQUS software to analysis characteristics and failure mode of foundation is correct and reasonable.
