Abstract: Although parametric modeling has garnered widespread attention, its application in hydraulic structures, especially in aqueduct structures, remains relatively under-researched. To enhance the digital application of hydraulic aqueducts, this study conducts parametric modeling and application research for aqueduct structures using the Revit platform, focusing on the Dongjiacun aqueduct. By defining the key parameters of the aqueduct structure and their relationships, users can flexibly adjust the shape and dimensions of the aqueduct by modifying these parameters, enabling quick iterations in design and optimization. In the future, parametric modeling is expected to become a mainstream method in aqueduct design, improving design efficiency, precision, reliability, and standardization.
