Abstract
This invention relates to the field of structural optimization technology, specifically to a method for optimizing the design of aqueduct structures based on BIM technology, which solves the technical problem of low accuracy in the optimization design of aqueduct structures in existing technologies. The method includes: acquiring a BIM model of the aqueduct structure; performing finite element model conversion and mesh generation on the BIM model to obtain a finite element model; performing various dynamic load simulations on the finite element model to determine a first refinement region requiring refinement based on the load; identifying the joint regions of the aqueduct structure based on the geometric features of the BIM model to determine a second refinement region requiring refinement based on the joints; refining the meshes of the first and second refinement regions and updating the BIM model based on the refinement results; and optimizing the aqueduct structure based on the updated BIM model.
