Application Of Bim Technology In The Information Construction Of Bridge Engineering

Based on Revit software,this paper develops a Dynamo modeling program to automatically generate a full-bridge BIM model.The lightweight processing of BIM models is combined with WebGL technology and digital twin technology to develop a visual monitoring platform for bridges equipped with BIM models.Mainly carried out the following work:Discusses the origin of BIM technology and its main application on smart transportation platforms,compares and analyzes the advantages and disadvantages of the BIM series platforms currently widely used in engineering,and chooses Revit as the core modeling software.The design ideas of the Revit parametric family are expounded,and the standard component family of bridges is taken as an example to further introduce the advantages of parametric,and highlight its significance to Dynamo’s automatic modeling.In order to improve modeling efficiency,a parametric family with high reusability in bridge engineering has been established,such as pile foundations,pier columns,T beams,wet joints and diaphragms,etc.;Dynamo parametric automatic modeling program is designed,Achieve the purpose of automatically generating BIM models by reading excel table information.Relying on the background of the Taoyuan Bridge in Zezhou County,Jincheng City,the full bridge model was established in accordance with the Dynamo modeling program designed in this article,and parametric information was given to realize the automatic parametric modeling of the bridge,which verified the feasibility and tradition of visual programming The superiority of modeling methods compared.The bridge monitoring platform is developed based on the B/S architecture to realize monitoring data upload,analysis chart generation,early warning level setting,over-limit data export,email reminder,historical record query and other functions.The BIMFACE engine is used to lighten the BIM model,combined with WebGL technology and digital twin technology,the BIM model is embedded in the monitoring platform,and the city model is built through the virtual engine,which beautifies the platform user interface and highlights the comprehensive advantages of BIM technology and the monitoring platform.Improve the visual management level of bridge operation and maintenance.
