面向多源数据集成的高速公路数字化方法研究

高速公路具有线路长、地形复杂,工程设计施工难度大,且涉及多专业交叉等特点,为了在Web端更加便捷、清晰、直观地展示并管理道路、桥梁等数据,通过结合当前被广泛运用于实际工程项目的 BIM技术、Web GL、倾斜摄影技术等,提出基于开源三维地图引擎Cesium的高速公路数字化方法,在数字地球上集成BIM及GIS领域的多源异构数据,为基础设施提供真实的地理环境,地理环境也将拥有更多立体的基础设施,并使地形、道路信息模型等能够跨平台、跨终端地进行三维展示及交互,实现对工程项目从宏观至微观的把控以及设计成果的可视化数字交付。将该方法成功应用于北京延庆某山区高速公路项目中,为行业建设提供应用参考,为公路的全生命周期管理奠定基础。

Highway Digitalization Research for Multi-source Data Integration

The highway has long lines, complex terrain, difficult engineering design and construction, and involves multiple professional crosses, In order to display and manage roads, bridges and other data more conveniently, clearly and intuitively on the Web side,combine BIM technology, WebGL, tilt photography, etc., which are currently widely used in practical engineering projects, proposed a highway data management method based on the open source three-dimensional map engine cesium, the multi-source heterogeneous data in the BIM and GIS fields is integrated on the digital earth, which solves the problem that the traditional two-dimensional GIS cannot completely reflect the three-dimensional world and the plug-in Web compatibility is poor, so that the terrain and highway information models can be displayed and interacted cross-platform in three dimensions, providing a true geographical environment for the infrastructure, and the geographic environment will also have more three-dimensional infrastructure to achieve macro-to-micro control of engineering projects and digital delivery of design results. The method is successfully applied to a highway project in a mountainous area in Yanqing, Beijing, which provides application reference for industry construction and lays a foundation for the whole life cycle management of the highway.
