为了解决高速铁路领域中多专业协同建模与模型信息共享重用的问题，以面向对象的思想自上而下地对高速铁路场景进行剖分，构建高速铁路不同专业领域的基元模型库，然后基于Oracle关系数据库，实现三维模型的存储、查询、共享等管理机制，通过对数据库中的三维模型进行有效的调度和组合，再对处理后的影像和地形进行叠加、匹配，即可生成虚拟高速铁路场景。结果表明，该方法能够采用数据库技术对三维模型进行有效的管理和调度，进而利于生成虚拟场景。研究成果能够为高速铁路提供建模服务。

For the problems about multi-discipline collaboration modeling and model information sharing and reusing in the high-speed railway field,this paper introduced the way to generate a virtual high-speed railway scene.Firstly,to establish basic element bases of different professional fields of high-speed railways,this paper gave a top-down subdivision to the high-speed railway scene based on object-oriented ideas.Secondly,it implemented management mechanisms for the storage,query and share of 3D models based on Oracle relational database.Finally,through effectively scheduling and combining the 3D models in the databases,then constructed the virtual high-speed railway scene by matching the processed images and terrains. The research results show that the 3D models can be managed and scheduled,which favored the construction of the virtual scene.The proposed method can provide modeling services for high-speed rail.
