摘要：
Aiming at the combined bearing characteristics of the four-bucket jacket foundation of offshore wind turbine in sandy soil，the numerical simulation method is used to calculate the ultimate bearing capacity of the four-bucket jacket foundation under five different loads combinations. Taking the bucket diameter，bucket height，and bucket spacing of 15 m as the control group，changing the bucket height and suction bucket center distance，and the failure enrelopes were drawn. The results show that under the action of vertical load，the horizontal ultimate bearing capacity of the foundation increases first and then decreases. The torsional bearing capacity of the foundation also increases with the increase of the vertical load and decreases with the increase of the horizontal load. Under the action of different vertical loads，the horizontal and moment ultimate bearing capacity are basically linearly related. © 2024 Science Press. All rights reserved.
