摘要
探讨地铁辅助线的设计方法及注意事项,包括:车辆段出入线一站或两站接轨方案的优缺点及接轨方式,出入线与正线立交需要的最小上、下线轨面高差和最小线间距诸因素的计算,一度停车位置的选定及如何满足缓坡设置的方法,一种小交路站前折返平面布置新图型,折返方式不同引起了安全保护距离有区别,停车线平面布置中安全线设置的推敲、最小线间距及有效长所考虑的因素,存车线需要的最小线间距、纵断面设计要求,安全线设置规定中的矛盾、探讨及信号制式对其设置的要求,道岔防护信号机与道岔间及道岔与站台间的距离要求等。
In this paper, the design methods for auxiliary lines on subway and some comments involved are described In detail, including the merits and defects of the one-station and two -station junction modes for the exit and entrance lines of the depot; calculation of the track level difference between the exit and entrance line and the main line on the crossover, and of the minimum distance between tracks; selection of the position of the stop once and the layout of transition grade; a new pattern for the plan layout of small round trip turn back in front of the station; installation of safety siding In the plan layout of siding lines; minimum track distance and longitudinal profile for the siding lines; requirements for layout of the safety line by signal system; required distances between orotection signal and switches, and distances between switches and station platform, etc.
