基于.NET6的铁路BIM可视化综合应用系统研究

针对现有建筑信息模型（BIM,Building Information Modeling）+地理信息系统（GIS,Geographic Information System）可视化方案部署和应用复杂、依赖商业软件、要求带宽高等问题，研发并设计了基于.NET6技术的铁路BIM可视化综合应用系统。通过工业基础类（IFC,Industry Foundation Class）文件解析转换、数模分离及属性数据存储等技术，实现了BIM解析、部署、应用一体化及动态场景演示等功能。该系统可对铁路单工点、单场段、车站等范围内的BIM成果进行部署和应用，是对现有BIM+GIS大体量模型部署方案的有效补充。系统的应用有利于现阶段BIM成果发挥更大的应用价值，为实际工程项目灵活部署提供参考。

Railway BIM visualization comprehensive application system based on .NET6

Aiming at the problems of the BIM+GIS visualization application scheme, such as complex deployment and application, dependence on commercial software and high bandwidth requirements, this paper developed and designed a set of railway BIM visualization comprehensive system based on .NET6 technology. The paper implemented the BIM model parsing, deployment, application integration, model data cloud publishing, local caching and other functions through technologies such as Industrial Foundation Class (IFC) file parsing and conversion, digital analog separation, and attribute data storage. The system can deploy and apply the BIM model achievements within the scope of railway simplex points, single yard sections, stations, etc. It is an effective supplement to the existing BIM+GIS large-scale model deployment scheme. The application of the system is conducive to the BIM achievements at this stage to play a greater application value, and provides a reference for the flexible deployment of actual engineering projects.
