Abstract：The shallow buried bucket foundation is a new type of offshore wind turbine foundation, which has the great advantage of controlling differential settlement in clay ground. But the design method of shallow buried bucket foundation is still premature at present, and the bucket and soil inside the bucket is usually taken as a whole when designing the bucket foundation. Based on bucket-soil uncooperative phenomenon and earth pressure distribution in the large scale model test, the concept of bucket-soil cooperative degree is defined. The influences of the parameters, including loading condition, dimension of bucket foundation, bucket compartment form, height and thickness of bulkheads and bucket-soil relative stiffness, on bucket-soil cooperative degree were analyzed using numerical simulation method. The influence of bucket-soil cooperation on the bearing capacity of bucket foundation was studied in order to provide reference for optimal structural design of the foundation.
