BIM技术在改扩建公路桥梁勘察设计中的应用研究

依托交通运输部第一批"公路BIM技术应用示范项目"——京沪高速公路莱芜至临沂(鲁苏界)段改扩建工程,针对典型桥梁改扩建方案,从GIS勘察、既有桥梁结构BIM还原、自动化BIM设计建模、可视化施工模拟等方面,论述BIM技术在改扩建公路桥梁勘察设计中的应用。对具体桥梁改扩建实例的分析表明,GIS+BIM技术可充分发挥其信息化和可视化的特点,还原既有桥梁、复核设计数据,利用一套数据开展多阶段BIM设计和辅助施工模拟等,提升改扩建桥梁勘察设计质量,优化工程设计,保证项目的顺利开展。

Application Research of BIM Technology in Survey and Design ofReconstruction and Extension of Highway Bridges

Based on the first batch of“Application Demonstration Project of Highway BIMTechnology”of the Ministry of Transport,the reconstruction and extension project of Laiwu-Linyi(boundary between Shandong and Jiangsu provinces)section of the Beijing-Shanghai Expressway,in thepaper,the application of BIM Technology in the survey and design of reconstruction and expansion ofhighway bridges is discussed from the aspects of GIS survey,BIM reduction of existing bridge structure,automatic BIM design modeling,visual construction simulation,etc.Through the analysis of specificbridge reconstruction and expansion projects,GIS with BIM technology can give full play to itsinformational and visible features,restore the existing bridge,review the design data,use a set of data tocarry out multi-stage BIM design,facilitate construction simulation,etc.These methods can improve thequality of survey and design,optimize the design,and ensure the smooth development of the project.
