新建铁路线路计算机辅助设计研究与开发

Research and Development of Computer Aided Design for New Railway Line

研究目的:铁路工程建设进入快速发展期,项目规模大,建设标准高,为了满足项目设计的需要,迫切需要更新设计手段,有必要开展以矢量地形图为选线参照物,充分利用三维数据研究开发计算机辅助选线设计系统软件。达到提高生产效率,提高设计质量的目的。研究结论:在综合分析各等级新建铁路线路勘测设计流程的基础上,开发了线路计算机辅助设计软件系统,解决了软件系统开发的数字地面建模、图形与数据联动、线路平纵横联动,铁路Ⅱ线的动态交互设计、线路方案管理、线路设计的实时三维可视化等关键技术。开发成果的应用表明,利用这些技术开发的线路计算机辅助设计系统可以在工程设计中推广应用。

Research purposes： Chinese railway construction develops rapidly with large scale and high standard, so it is necessary to research and develop the CAD software for route selection based on 3D data, taking vector landform diagram as reference for the purpose of satisfying the requirements of construction design. In this way, we can achieve the aim of enhancing production efficiency and improving design quality. Research condusions：Based on the analyses of survey and design flows of new railway lines at different grades, CAD for railway line are presented and researches are done on the key technologies of establishing digital ground model, interaction of the graph with the data, the interactions of track plane section, track longitudinal section and track lateral section, interaction design of railway ]] line, track scheme management and real 3D visuals of design. The application results show the CAD based on these technologies can be generalized and applied in the construction design.
