摘要
研究了利用三维可视化技术开发城市地下空间信息平台的方法,提出信息平台的总体架构和系统功能设计,分析并解决了信息平台开发中遇到的三维动态加载、二三维联动、BIM和LOD等关键技术,实现了地上地下三维集成展现,并以南宁市为例开发了完整的三维地下空间系统,为城市地下空间的开发利用提供辅助决策和技术支撑。
In order to improve the rationality and scientificity of underground space planning, construction and management, we studied the method of developing urban underground spatial information platform by using 3D visualization technology, and put forward the overall architecture and system function design of this platform. Then, we analyzed and solved the key technologies such as 3D dynamic loading, 2D and 3D linkage, BIM and LOD for developing of information platform. Finally, we realized the 3D integrated display on the ground and underground and developed a complete 3D underground space system for Nanning City, which could provide auxiliary decision-making technology support for the development and utilization of urban underground space.
