Study On The Visualization Of Bridge Disease

In view of the problem that the traditional bridge disease information record is not intuitive enough and the description is not clear enough,this paper puts forward a new method to realize the visualization of bridge disease information based on BIM,and effectively solves the problem of disease information recording.Through the REVIT software platform and IFC data description standard,this paper studies how to rephrase twodimensional abstract bridge disease information as IFC statements,so as to realize the visual expression of bridge disease information in REVIT software.In order to visualize bridge disease information,this paper mainly discusses the following four contents:1)Based on the EBS coding standard and method,the EBS coding decomposition standard of bridge engineering projects and its implementation process are discussed.By realizing the standard coding of bridge components,we can greatly simplify the complexity of information storage and extraction of bridge components,and improve the efficiency of search and query.2)The parametric modeling of bridge components is realized based on REVIT and Dynamo software by setting the component model parameter information and the bridge overall parameter information.By summarizing the parameter information necessary to record the three-dimensional model of bridge components,this paper obtains the concrete implementation method to realize the parameterization model of the bridge component 3D model,and realizes the parametric model of bridge model by Dynamo command flow.3)By discussing the compilation principle of IFC file,the relevant syntax format and function of IFC statement sit in detail.The specific compilation process of IFC statement implementation geometry model is studied in detail,and the corresponding IFC statement compilation method is obtained.4)Based on IFC files and Dynamo command flow,the visual modeling process of common bridge diseases,including cracks,concrete breakage,and ribs,is realized.The feasibility and practical value of the disease information visualization method are discussed in combination with the engineering.
