通过对虚拟高速铁路场景对象实体、三维关系进行详细分析，提出了基于实体-关系概念模型的虚拟高速铁路场景组合建模方法，设计了分层（实体层、关系层、场景层）描述的虚拟高速铁路概念场景模型，给出了模型基元分类建模方法，并详细讨论了虚拟高速铁路概念场景的构建流程和基元模型映射组合机制等关键技术。在此基础上，构建了原型系统，并选择案例区域开展了试验。案例区试验结果表明，110 km线路场景建模可在2 min内完成，本文的方法能够有效地理清各场景对象实体和实体之间的关系，可支持虚拟高速铁路场景的快速组织与建模。

By analyzing the object entity and the three dimensional relations of virtual high-speed railway scene,a combinational modeling method based on entity-relationship conceptual model was proposed. The conceptual model of virtual high-speed railway scene was designed,which includes three levels,namely entity level,relation level and scene level. Then some key technologies such as modeling flowchart,mapping and combination of primitive models were discussed in detail. Finally a prototype system was implemented for modeling experiment on a case study region. The experimental results show that 110 km line scene modeling can be finished within 2 min. The proposed method can efficiently clarify various relations between scene object entities. It supports fast organization and the modeling of virtual high-speed railway scene.
