Abstract

The invention discloses a BIM-based tunnel main body structure reinforcing steel bar IFC2x3 data visualization method. The method comprises the steps of creating a tunnel main body structure reinforcing steel bar model drawing file according to a tunnel main body structure reinforcing steel bar two-dimensional drawing; exporting an IFC2x3 standard file from the tunnel main body structure steel bar model drawing file according to a layer; analyzing a mapping relation between the IFC2x3 standard file and the DGN file, and establishing data mapping between the IFC2x3 standard file and the DGN file; converting the tunnel main body structure reinforcing steel bar IFC2x3 file model into a DGN file by using a data interface; using a plug-in of Microstation software, setting the conversion parameters, and converting the DGN file into a UDBX file; extracting attribute information of a tunnel main body structure reinforcing steel bar by using SuperMap iDesktop, and converting a UDBX file into a tile data S3M file; visually displaying the tunnel main body structure reinforcement model of the tile data S3M file on a BIMiServer platform, and checking the reinforcement model and engineering quantity information of the reinforcement model. The problem that conversion among different three-dimensional data formats is incompatible is solved, and efficient browsing of the reinforcement model is achieved.

Description

technical field [0001] The invention relates to a BIM-based method for visualizing IFC2x3 data of tunnel main structure reinforcement, belonging to the technical field of BIM model information visualization. Background technique [0002] At present, steel bars are one of the important materials in tunnel engineering. Traditional tunnel main structure steel bar drawing is based on CAD (Computer Aided Design, computer-aided design) to create two-dimensional drawings. It is impossible to check the steel bar engineering quantity and the conflict between steel bars. Information Modeling (Building Information Modeling) technology to realize the visualization of the model has become an inevitable trend. With the in-depth application of BIM technology in the field of transportation infrastructure, the BIM model has gradually extended from planning and design to construction, operation management and decision-making. However, for the steel bar model of the main structure of the tunn...
