三维GIS在地铁车站综合管网设计中的应用研究

为了提高地铁车站综合管网的设计质量和效率，以虚拟现实技术为指导，自主研发了基于三维GIS平台的地铁车站综合管网信息系统。该系统以信息统筹管理、多信息数据集成、智能分析为设计目标，由数据层、逻辑层和应用层构成系统逻辑结构，其主要功能有图纸管理、图库管理、碰撞冲突分析、剖面功能、路径漫游和模型调整。以工程实际应用为依托，构建了基于三维GIS应用的地铁车站综合管网设计组织结构与协作模式。实践表明，三维GIS技术在地铁车站综合管网设计中的优势突出表现为突破设计难点、积累项目信息与节省建设成本，可为相关工程应用提供借鉴。

Research on the Application of 3D GIS in the Design of Integrated Pipe Network in Metro Station

In order to improve the quality and efficiency of integrated pipe network in metro station design, guided by virtual reality technology in theory, a integrated pipe network information system of the metro station which based on 3D GIS platform was independently researched and developed. The design objectives of the system were general control of integrated network information of the metro station, construction of multi-information and data integration, intelligent control and analysis and so on. Logical structure of the system included data layer, logic layer, and application layer, and the system had six functions which included drawing management, model library management, integrated pipe network conflict analysis, profile function, path navigation and model adjustment. Based on the practical engineering, organization structure and cooperation mode of the integrated pipe network design of the metro station had been built based on application of 3D GIS. The practice had shown that the advantage of the 3D GIS technology was to point out design difficulties, accumulating project information, saving construction cost. It can provide references for related engineering application.
