铁路线路设计回顾与思考

研究目的:铁路选线设计是涉及面广、技术性强、关系全局的总体性工作,也是一项复杂的系统工程。本文就铁路线路设计手段从以人工与图板为主,发展到甩掉图板,运用计算机辅助设计系统进行了平面、纵断面、横断面优化设计等方面进行了回顾,阐述了线路设计技术的进步、创新与发展方向,从而就铁路线路设计标准的提高和不断发展提出铁路线路设计需解决的关键技术问题及研究课题。研究结论:尽快由三维设计环境向多维设计环境发展,由计算机辅助设计向人工智能设计发展,建成数字铁路远线专家系统,是铁路选线设计技术的一次重大革新。必将大大提高铁路选线设计的生产效率,缩短工程设计周期,提高设计质量。

Review and Thoughts on Alignment Design of Railway Line

Research purposes: Alignment design of railway line is a complicated systematic engineering with involving matters of all aspects,requiring high technicality and having significance to the integral work of entire construction.In this paper,the review is made for the development experience of the design means for alignment of railway line from making design manually by using drawing board to making design with using CAD System instead of drawing board to draw plane drawing,vertical section drawing,the ideas are expressed on the issues of the progress,innovation and(development) direction of design technology for railway line,and the key technical problems to be solved and research projects are pointed out for design of railway line with continuous improvement and development of design standard of railway line. Research conclusions:It is necessary to make development of multidimensional design environment from 3-dimensonal design environment and make development of manually intelligent design from CAD.Establishing digital railway(alignment) experts system is a great innovation for the technology of railway alignment design.In this way,the production efficiency of railway alignment design can be much improved,the design time can be shortened and the design quality can be improved.
