【摘要】：研究目的:数字地球平台(如Google Earth)提供了全球丰富的数字地形和数字影像资料。在铁路项目前期研究中,如何快速获取研究区域内的地形高程数据,构建三角网数字地面模型,应用CAD、可视化、人机交互等技术,是实现线路交互式联动可视化,完成线路选线设计的基础。本文阐述了"铁路各设计阶段数字选线平台"在新建铁路项目前期研究,尤其在缺少矢量化地形图的国外铁路项目中的应用过程,以实际项目证明了软件的应用价值。为类似软件的推广应用提供了有益参考。研究结论:(1)"铁路各设计阶段数字选线平台"已广泛应用于我院承担的国内外前期项目研究的选线设计工作中,从而实现了将传统的二维静态设计提升为三维动态设计,显著提高线路设计的效率和水平;(2)"铁路各设计阶段数字选线平台"的应用,可大大降低设计人员的工作强度,提高设计质量。
[Abstract]:Purpose: digital Earth platforms such as Google Earth) provide global digital terrain and image data. In the early research of railway project, how to quickly acquire terrain elevation data in the study area, construct the digital ground model of triangular network, apply CAD, visualization, human-computer interaction and other technologies, is to realize the interactive visualization of the line. Complete the basis of line selection design. This paper describes the application process of "Digital Line selection platform for each Design stage of Railway" in the early stage of the new railway project, especially in the foreign railway project which lacks vectorized topographic map. The application value of the software is proved by the actual project. It provides a useful reference for the popularization and application of similar software. The conclusions are as follows: (1) the "Digital Route selection platform for each Design stage of Railway" has been widely used in the route selection work undertaken by our hospital in the previous research projects at home and abroad, thus realizing the upgrading of traditional two-dimensional static design to three-dimensional dynamic design. Improving the efficiency and level of line design; (2) the application of "Digital Route selection platform for each Design stage of Railway" can greatly reduce the working intensity of the designers and improve the design quality.
