摘　　要：目前我国各铁路设计单位面临的既有线改建设计任务日益繁重,但国内针对既有线改建计算机辅助设计方面的研究较少,现有的线路设计CAD系统仍不能满足设计需求。在此前提下,文章以中铁二院"改建铁路数字化选线系统"为研究背景,分析了系统的功能结构和关键技术,采用VisualC++.NET2002开发平台以及ObjectARX二次开发技术,研发了改建铁路数字化选线系统,并成功地应用到成渝等既有铁路的改建设计中。At present, China＇s railway design companies are burdened with tough tasks to reconstruct existing lines. However, they face problems of insufficiency of research on computer assistant design in this field and the existing CAD system for route design can not yet meet requirements for design. In such circumstance, this paper analyzes the system＇s function and structure as well as key technologies of the Digital Line Selection System for Reconstruction of Railway designed by CREEC, which employs Visual C ＋ ＋. net2002 developing platform and Object ARX secondary development technique to research and develop the Digital Line Selection System for Reconstruction of Railway and it has been successfully applied in design for reconstruction of Chengdu-Chongqing existing line, etc.
