摘要：
The integration technology of BIM and 3DGIS is proposed. The first step of this technology is to convert the BIM generated by Revit software into a fast lossless format for 3DGIS. The geometric information of BIM is transformed into a *.dae format file acceptable to 3DGIS and the attribute information of BIM is saved to the database. The *.dae format file is associated with the database by using the ID of the element as the unique field. The second step is to integrate BIM with 3DGIS, including the unification of coordinate system, the information reading and transformation of attitude, azimuth and scale factors, the traversal reading and saving of model transformation files, the comprehensive integration of BIM information and spatial expression in 3DGIS. By using C# programming language and SQL Server database, the railway bridge construction management information system based on the integration of BIM and 3DGIS is developed and applied in the construction project of a super large bridge of Menghua Railway. Results show that the system integrates a large number of BIM models of railway bridges such as 215 piers, 212 beams and 2 continuous beams into 3DGIS in batches. The problem of data sharing and data mining between different stages of design, construction and management is solved. The functions of 3DGIS visualization, roaming and 3D spatial analysis, BIM construction management, the dynamic simulation of construction and the overview of construction progress are realized. © 2019, Editorial Department of China Railway Science.
