摘　　要：针对地铁工程项目可视化管理中存在的模型精细化不足、数据集成与展示不充分及真实性欠缺等问题,本研究提出了利用GIS和BIM技术作为解决方案,提升地铁工程实景三维建设的效果。首先研究构建了地铁工程实景三维平台的建设框架,分析了数据集成与融合、动态层次加载、模型轻量化与显示等关键技术。随后以深圳地铁14号线工程为案例,进行了实景三维可视化平台的建设与功能应用。案例涵盖了工程建设管理图、空间分析可视化、多视角场景漫游及BIM可视化与属性查询等内容,实现了地铁工程项目多源异构数据与模型的集成,提供了多尺度的实景三维可视化展示,为项目管理与决策提供了有力支持。This study addresses the challenges in visual management of subway engineering projects,including insufficient model refinement,inadequate data integration and display,and a lack of authenticity in visualization.GIS and BIM technologies are proposed as solutions for real-scene 3D construction visualization in subway projects.The research first establishes a framework for developing a real-scene 3D visualization platform for subway engineering,analyzing key technologies such as data integration and fusion,dynamic hierarchical loading,model lightweighting,and display.Subsequently,a case study of the Shenzhen Metro Line 14 project is presented,focusing on the construction and functional application of the real-scene 3D visualization platform.The case study includes engineering construction management maps,spatial analysis visualization,multi-view scene navigation,and BIM visualization and attribute queries.This approach facilitates the integration of multi-source heterogeneous data and models,providing multi-scale real-scene 3D visualization and offering robust support for project management and decision-making.
