Abstract :
This paper discusses the 3D informatization modeling with the technology of the information and visualization, which can help the collaborative network design, guide pipe network construction, and auxiliary network operations management. The concepts and the top use-case diagram are given firstly. According to building the rail transit real experiences and requirements, the function frame is proposed. And the corresponding logic architecture is shown with UI layer, application layer, logical layer and data layer from top to bottom. Furthermore, the database is discussed and design. The Family Library is created based on parametric modeling for processing the model better. And the data warehouse is established to process the multi-source data in the different phases. In order to build the model easily to be operated by the different persons, some standards are established: express the data object with the different color, some annotation are added to express the visual information, 2D and 3D data are jointly shown by 3D Gis, the technology of point cloud is used to monitor construct.Finally, some implementations are shown. The model has been applied in constructing Ningbo Rail Transit, it runs well, reduces the cost, improves the quality of the project, and has played a very good demonstration effect.
