Regarding the problems such as low degree of standardization, large workload of concrete pouring, multiple ship and machine equipment, and high safety risk of construction crews during the building of high-piled wharf by using routine techniques, this paper combined with the design and construction of multiple wharf projects in Xuwei Port Area of Lianyungang Port.The application technology and effectiveness of prefabricated pile caps, prefabricated beams and modular components technologies used in high-piled wharf structures are studied.The results show that the prefabricated technical proposal for wharf engineering should be determined by combining the natural conditions of the project area, the requirements of berth use, the size of the main structure and the construction capacity, and should be supplemented by the necessary innovative measures of node connection.The application of prefabricated technology in Xuwei Port Area can provide references for similar projects.
