摘　　要：既有地铁线路会因运营需求对线路通过插入道岔的方式进行贯通改造。论文结合地铁既有线贯通改造工程案例,通过对既有线路现状条件、新插入组合道岔线间距过小需特殊设计等难点进行分析,详细阐述了组合道岔设计研究过程。Existing metro lines would be transformed by inserting switches because of operation requirements.In this paper,combined with the case of the existing metro line through reconstruction project,through the analysis of the current conditions of the existing lines and the difficulties in the special design of the newly inserted combined turnout line spacing is too small,the design and research process of the combined turnout is described in detail.

关 键 词：既有地铁线路 贯通改造 组合道岔 设计研究
