计算机软件在铁路选线设计中的应用研究

Research on the application of computer software in the design of railway line selection

基于在虚拟的立体地理环境中进行铁路选线设计的目标,构建一个以立体地理环境为基础的铁路选线设计系统。结合信息技术、数字技术、遥感技术、虚拟技术和卫星技术等,创建一个相对真实的铁路地理环境;采取BIM技术,建立铁路基本构造元数据库;利用数据库中的基本元构件,建造铁路选线立体模型,并且能不断检查和维护。实现铁路选线设计的三维立体化。铁路选线系统可让线路设计师在虚拟环境中进行线路考察和分析,快速建造铁路选线立体模型,该模型具有直观性、灵活性等特点,符合地理环境选线、重大铁路工程优先选线、跨国铁路选线等的标准。

Objective：to build a railway line selection system based on the three-dimensional geographical environment, based on the goal of the railway line selection in the virtual three-dimensional environment. Methods：the combination of information technology and digital technology, remote sensing technology, virtual technology and satellite technology, to create a relatively real railway geographic environment ;the adoption of BIM technology, build the basic structure of the meta database;using the basic component in the database, the construction of the railway line selection model, and constantly check and maintenance. Results ： to achieve the three-dimensional design of railway line selection. Conclusion ： can let the line designer line investigation and analysis in the virtual environment railway system, rapid construction of three-dimensional model of the railway line selection, the model has the characteristics of intuition and flexibility, with the geographical environment, major railway line selection priority line selection, cross-border railway standard etc.
