摘　　要：随着BIM技术及无人机倾斜摄影测量技术的发展,开展BIM、GIS等信息化技术在铁路行业的应用研究,对铁路工程的信息化管理具有重要应用价值。针对某铁路车站改建工程,采用BIM及倾斜摄影测量技术,进行BIM+GIS数据集成应用。对车站改建范围内轨道、轨枕、路基、涵洞、人形天桥、四电设备等进行BIM建模;采用无人机对车站进行航拍摄影,生成车站三维实景模型;在GIS平台中,将车站BIM模型和三维实景模型进行融合,完成场景搭建;最后基于BIM+GIS+倾斜摄影模型,对车站改建施工过程进行可视化展示。利用北斗高精度定位技术,在改建施工过程中,对作业人员进行安全防护。With the development of BIM technology and drone tilt photogrammetry technology,the application of BIM,GIS and other information technology in the railway industry has important application value for the information management of railway engineering.For a railway station reconstruction project,BIM and oblique photogrammetry technology is used for BIM+GIS data integration application.BIM modeling is performed for tracks,sleepers,subgrades,culverts,humanshaped flyovers,and four electrical equipment within the scope of the station required to be reconstructed.Drones will be used to take aerial photography of the station to generate a three-dimensional real-world model of the station.In the GIS platform,the BIM model of the station and the 3D real-world model are integrated to construct the scene.Finally,based on the BIM+GIS+oblique photography model,the construction process of the station reconstruction will be displayed step by step.By using the BeiDou high-precision positioning technology,the safety protection for operators can be achieved during the reconstruction and construction process.
