在分析英国的MOSS、美国的InRail与InRoad、德国的CARD/1等选线软件及澳大利亚旷达线路三维优化规划系统的基础上,开发了具有实时平纵横三维联动和动态仿真可视化的计算机辅助选线系统。介绍系统的主要功能及关键技术:快速整体构建数字地面模型算法,夹点驱动平纵断面设计参数与平纵横实时三维联动显示,线路三维可视化与虚拟场景仿真。在武广、郑西客运专线勘测设计中,该系统发挥了重要的作用,已成为客运专线选线设计必不可少的设计平台。
Based on the analysis of MOSS in the United Kingdom, InRail in the United States and InRoad in the United States, the CARD / 1 routing software in Germany and the three-dimensional optimization planning system of Australia’s Unconstrained Line, a computer-aided alignment with real-time vertical and horizontal 3D linkage and dynamic simulation was developed system. This paper introduces the main functions and key technologies of the system: fast and overall construction of the digital terrain model algorithm, the design parameters of pinch-driven flat longitudinal section and the real-time three-dimensional display of horizontal and vertical cross-links, the line three-dimensional visualization and the virtual scene simulation. In the survey and design of Wuhan-Guangzhou and Zheng-Xi Passenger Dedicated Line, the system has played an important role and has become an indispensable design platform for the design of passenger dedicated line route selection.
