摘　　要：研究目的:地铁线路设计是重要的环节,确定的设计参数直接影响工程造价。本文针对辅助线、曲线线间距、坡度等线路涉及的设计内容进行探讨,把理论和具体做法通过实例总结出来,给线路设计提供一些借鉴和帮助。研究方法:结合沈阳地铁线路设计经验,采用几何和代数方程方法进行研究。研究结果:通过研究地铁线路设计中相关参数,得出有效长度、渡线、线间距、节能坡度等计算公式,并阐述了设计中结构限界、轨道类型、信号制式等对线路设计的影响。研究结论:本次研究的计算方法,表明地铁的线路设计与轨道、信号等参数密切相关,不同参数决定不同的设计内容。要进行不同的方案比选,才能得出合理的线路设计方案。Research purposes： The design of metro line is an important step and the decided parameters have effected on the engineering cost directly. This paper discusses the auxiliary line, distance between the two lines in curve and grade, sums up the theories and material design, and provides the reference and help for the line design . Research methods：The geometry and algebra equation are used in the course of research combining with design experience in Shenyang Metro. Research results： Through studying the correlative parameters of the metro design, this paper educes computing formula of the effective length, cross - over, distance between the two lines and economical grade, and sets forth the influence of structure delimitation, track style, signal system on the design of line. Research conclusions：The studying of calculational method explains the close relations of metro line, track and signal. The different designs depend on different parameters. We need comparison and choice of different plans, so reasonal line plans will be attained.
