| BIM(Building Information Modeling)has already been well known for its efforts in improving the high-efficiency of the AEC(Architecture,Engineering,and Construction)industry.Meanwhile,there has been a rising trend for the support of a web display developed by HTML 5(HyperText Markup Language)and WebGL(Web Graphics Library)technology in BIM.As a critical technical method of 3D(three-dimensional)modeling and data visualization,BIM and WebGL integration technologies are becoming more and more widely used in digital management of engineering structure health monitoring and information display.Aimed at the problems of the information visualization direction of APMS(Airport Pavement Management System),the application of BIM and WebGL technology in engineering 3D visualization was investigated and analyzed,and the functions and deficiencies of representative APMS at home and abroad were summarized.Therefore,the framework and research of APMS based on BIM and WebGL are studied,and the specific development ideas of the system are proposed.Firstly,according to the established platform management system framework and functional and performance requirements analysis,the functional modules of the system are designed,which including pavement basic database management system,pavement 3D modeling system,3D visualization of pavement quality system,evaluation and early-warning of pavement quality system.Secondly,aimed at insufficient depth of pavement health status information,theMultiscale pavement quality technical parameter index system is researched,which includes periodic detection datas and real-time monitoring datas.Thirdly,aimed at the core requirement for the 3D visualization of pavement quality,the pavement 3D modeling is established based on pavement necessary data information and Revit software.The pavement unit modules and the “Family library” of disease markers are constructed,and the subsequent development of Revit based on the VS(Visual Studio)platform and C# programing language is programed.Then,the API visual Plugins are developed.Finally,two kinds of visualization methods in detection data are presented based on the general principles of information visualization and the integration of BIM and WebGL technology,includes the disease detection information visualization program based on the secondary development of Revit and the disease detection information visualization program based on the the integration of BIM and WebGL,which break through the limitations of traditional pavement quality inspection management,realize the 3D visualization expression of airport pavement quality information effectively,and provides thoughts for the future development direction of the intelligence and informatization in APMS. |
