摘　　要：为解决目前铁路行业电子沙盘存在的表达方式不一、应用内容单一、数据泄露风险大、数据加载效率低等问题,研究海量地理地质及BIM模型的数据处理、管理和应用方法,建立以BIM+GIS为技术核心的标准化电子沙盘,从而更好地服务于铁路设计和建造。根据鲁南高铁、拉林铁路、成渝中线高铁等项目实践总结,在中国铁路BIM联盟和国铁集团相关标准基础上提出了面向电子沙盘应用的地形、影像、BIM模型、专题图的数据制作标准,从坐标转换、数据转换、数据切片、知识图谱建立、模型发布、前端数据汇集的方法完成了电子沙盘的搭建。最后,在电子沙盘中实现了百公里级、多专业数据的在线高效组织和管理,提出的方法和标准适用于铁路设计、建设过程的管理和分析应用。In order to solve the problems existing in the current electronic sand table of railway industry,such as different expression methods,single application content,high risk of data leakage,low efficiency of data loading,etc.,this paper researches the data processing,management and application methods of massive geological and BIM models,and establishes a standardized electronic sand table with BIM+GIS as the technical core,so as to better serve the railway design and construction.Based on the practice summary of the projects such as Rizhao-Lankao High-speed Railway,Lhasa-Nyingchi Railway,Chengdu-Chongqing middle line high-speed railway and other projects,combined with the relevant standards of China Railway BIM Alliance and China Railway,this paper puts forward the data standards of terrain,image,BIM model and thematic map for the application of electronic sand table.And the establishment of it is completed through the processes of coordinate transformation,data transformation,data slicing,knowledge atlas establishment,model release and front-end data collection.Finally,the online efficient organization and management of hundred-kilometer-level and multi-specialty data is realized.The proposed methods and standards are applicable to the management and analysis application in railway design and construction processes.
