摘　　要：铁路枢纽内线路和车站数量较多、结构复杂,建模繁琐。为构建铁路枢纽网络数字化模型,基于AutoCAD枢纽图文档中既有的线路、车站等实体的特征数据,利用VS 2013建模,从DXF格式的数据文件中读取铁路枢纽网络实体的关键数据,建立实体数据间的业务关系,生成网络数字化模型,为研究、优化铁路枢纽网络提供数据支撑。该方法可降低建模工作量,有效提升工作效率。There are a large number of lines and stations in railway hub,with complex structure and complicated modeling.In order to build the digital model of railway hub network,the key data of railway hub network entity was read from DXF format data file by using the characteristic data of existing lines,stations and other entities in AutoCAD hub drawing document,and the business relationship between entity data was established.The network digital model was generated by using VS 2013 to provide data support for the research and optimization of railway hub network.The above modelingmethod can be used to reduce the workload of modeling and effectively improve the work efficiency.
