Abstract:

Using Revit software and parametric modeling ideas, a BIM model for the prefabrication stageof a high⁃speed railway segmental precast fully glued spliced prestressed concrete girder is established;Navisworks software is used to perform collision check on the various components of the segmental girder,and it is suggested that the BIM model is used in the design stage for optimization of the location ofprestressing pipelines and ordinary reinforcement; Based on the BIM model for prefabrication stage, itcan make statistics on the engineering quantity of prefabrication stage, provide help for formworkconfiguration,visualize the construction process, manage the construction personnel and equipments;BIM software can be used to analyze the virtual error of prefabrication size of segmental girders and dealwith it in advance,which is convenient for the subsequent prefabrication construction, and it can assist incontrolling the high⁃precision size and linear shape of the prefabrication stage of the segmental girders.
