Aiming at the problem of digital integration of bucket foundation structure design and construction，the application of BIM technology in the design and construction of bucket foundation structure is studied. In this paper，based on the breakwater project of District 4 in Xuwei Port District of Lianyungang City，combined with the design specification of bucket foundation structure and relying on BIM technology，the bucket structure breakwater design and structural calculation are combined，and the bucket structure family library construction and bucket structure are given. Based on the method，the integrated software for BIM design and calculation of bucket foundation structure are developed，and the design and construction connection interaction method based on BIM design results and the visualization method of bucket foundation structure construction and installation monitoring are proposed. It improves the quality and efficiency of the design and construction of the bucket foundation breakwater structure，and lays the foundation for the promotion of the new prefabricated bucket base.
