Research on failure mode and ultimate bearing characteristics of the single pile on different foundation

摘要

The most common forms of offshore wind turbine foundation are single pile foundation, but the loads and the overturning moment make it different from foundation of offshore oil platforms. The elastic-plastic element of the ABAQUS is to be used to simulate failure modes of pile foundation in soil clay. The results show that the single pile foundation has no plastic strain under ultimate vertical load in soft clay; pile foundation has plastic strain under the ultimate horizontal load; pile foundation has plastic zone in front of the pile under ultimate bending moment load.
