摘　　要：随着我国铁路信息化建设的不断推进,三维GIS和网络GIS在铁路领域中的应用逐渐深化。本文针对铁路线路三维场景空间信息服务,提出了基于三维开源引擎Cesium的铁路线路三维场景构建及网络应用方法,对Cesium架构与网络服务、线路三维地理环境构建、铁路工务基础设施工程组件三维模型构建进行了研究。为将铁路线路空间地理环境信息与铁路基础设施模型集成在Cesium三维引擎中,对铁路基础设施正向设计下的BIM模型进行了轻量化研究,实现了基于Cesium的网络化、跨平台、分布式铁路线路三维空间信息三维场景漫游、数据共享与功能服务。With the continuous advancement of China’s railway information construction, the application of 3 D GIS and network GIS in the railway field is gradually deepening. Aiming at the 3 D scene spatial information service of railway lines, this paper proposes a 3 D scene construction and network application method for railway lines based on the 3 D open source engine Cesium.The Cesium architecture and network services, the construction of the 3 D geographic environment of the line, and the construction of the 3 D model of the engineering components of the line and public works infrastructure have been studied. In order to integrate the spatial geographic environment information of the railway line with the railway infrastructure model in the Cesium 3 D engine, the lightweight research of the BIM model under the forward design of the railway infrastructure is carried out. It has realized Cesium-based networked, cross-platform, and distributed three-dimensional spatial information and 3 D scene roaming of railway lines, data sharing and functional services.
