In the background of smart port construction，building information modeling (BIM)technology plays an increasingly significant role in promoting the digital transformation of ports，and the data chassis of wharf infrastructure is built as a carrier to realize the multi-dimensional application of digital twins of wharf infrastructure.To explore the effective method of digital management and twin application of a high-piled wharf，based on Revit and its secondary development technology，and according to the structural characteristics of the high-piled wharf，this paper proposes a twinning modeling method connecting the BIM model and finite element model to build the BIM model of the high-piled wharf.The paper also develops an efficient model conversion program to accurately generate the finite element model of a high-piled wharf and verifies the correctness and rationality of the modeling method and conversion process by case application.
