为解决城市轨道交通工程各阶段多源数据集成问题、提升城市轨道交通运维监管效率与可视化效果,本文以三维地形数据的获取与发布、海量 GIS 数据的显示策略、BIM 模型数据的处理与加载为研究重点,提出一套实现 BIM+GIS 数据融合与地理位置配准的解决方案,并通过合肥市轨道工程验证。本研究使用 B/S 架构基于 Cesium 开源地图引擎,开发以 BIM+GIS 技术为核心的 Web 平台,该平台以 WebGL 为容器、Web 服务为链接,实现大范围真实地理空间环境下 BIM 模型的地理配准与对象级数据管理,同时实现了城市轨道交通实时监测与安全预警可视化展示,推动“云大物移智”融入城市轨道交通建设全生命周期,为城市轨道交通三维场景构建与数字化交付应用提供了参考。 |

In order to improve the multi-source data integration in all phases of urban rail transit project and the efficiency as well as thevisualization of urban rail transit operation and maintenance supervision,this paper focuses on the acquisition and publication of 3D terraindata,display strategy of massive GIS data,processing and loading of BIM data,and proposes a set of scheme integrating BIM+GIS datafusion and geographic alignment,which is verified by Hefei rail transit project. Using B/S architecture,Cesium and BIM+GIS technology asthe core,a Web platform is established,with WebGL as the container and Web service as the link for the geographic alignment and objectlevel data management of BIM model in a real,large scale geospatial environment,which realizes the real-time monitoring and safety warningvisualization of urban rail transportation. Integrating cloud computing,big data,IOT,mobile technology and AI into the whole life-cycle ofurban rail transit construction,the scheme provides a reference for 3D scene construction and digital application of urban rail transit. |
