摘要
在线路的三维建模中,路基三维模型与地形三维模型的交接、融合是关键技术和难点。首先分析了当前路基三维建模的方法,然后基于GIS平台,研究路基模型与地形模型的叠加,最后利用GIS控件实现了路基的三维建模和可视化。在实际铁路选线的应用中,证明了此方法的适用性和高效性。
The key technique to realize the roadbed 3D visualization is to establish an integrated roadbed and ground 3D model. Firstly, the current methods of 3D roadbed modeling are analyzed. Then, based on the platform of GIS, the integration of roadbed model and ground model is studied. Finally, the roadbed 3D modeling and visualization are realized by using GIS＇s groupware. The applications of this method in railway route selection are proved to be practical and efficient.
