The Research On Horizontal Bearing Capacity Characteristics Of Bucket Foundation For Offshore Wind Turbines Considering The Influence Of The Fluid Structure Interaction

With the development of modern society,countries around the globe now have increasingly demands on energy.Wind power,as we all know,is a type of energy featuring cost-effective,inexhaustible,clean and environmental friendly,as well as valuable in terms of commerce,getting more and more attention.In the past few years, the development and utilization of wind power in the seaboard have improved rapidly,at the same time,there are more higher requirement being put forward in the original wide-shallow bucket foundation soil property in offshore area is more complicated.The moisture content of soil is higher.The accuracy of results according to the fluid-structure interaction is under the results shich consider the bearing capacity of the fluid-structure interaction.So prople pay more attention to the research of fluid-structure interaction.Because of the complex interactions in the stress field and flow field,and water has a large effect on the shear strength of soil,we should lay emphasis on analyzing the bearing capacity of bucket foundation.In this essay,I use the large ABAQUS finite element software simulating the based 3D model of single tube type.And I compare the distinctions between the no bulkheads of bucket foundation bearing capacity of foundation in the influence of fluid-structure interaction.I also compare the differences of bucket foundation bearing capacity of bulkheads between the influence of fluid-structure interation.At the same time,I compare the distinctions between the bulkheads on the bearing capacity of the bucket foundation and no bulkheads under the influence of fluid-structure interaction.And I also point out the strengths and weakness which have the bucket foundation of bulkheads.In addition,I analyse the different depth under the influence of fluid-structure interaction and the varying pattern and failure mode of bucket foundation bearing capacity under the different soil parametors.In this research,I divides the soil mass into soil particles and pore water which can make the result more accurately. It also provides reference for the subsequent research of bucket foundation and the application of different conditions by using the comparison between bulkheads and no bulkheads.
