摘要
在阐述实现地铁跨线运行所需土建设施、车辆、供电、信号等主要条件的基础上,重点分析利用同站台换乘实现地铁跨线运行的方式及特点,并对其过轨方式、配线形式、平直线段最小长度等线路设计的技术问题进行深入研究。结果表明,利用同站台换乘方式实现跨线运行时,渡线联络线容易设置,采用站前过轨与站后过轨相结合的方式、选用9号道岔等方法可显著减少对平直线段长度的要求,是实现跨线运行的一种比较理想的方式。
The basic necessary conditions for joint operation of metro lines,such as infrastructure,vehicle,power supply and signal,are introduced. The ways to realize joint operation of metro lines by one-platform interchange and the corresponding characteristics are emphatically summarized. Some main technical problems in route design,such as modes of crossing lines,forms of siding lines and minimum length of plane straight line,are analyzed in detail. The research shows that the one-platform interchange is one of the ideal modes to realize joint operation of metro lines,for the transitional lines and the connecting lines can be laid easily,the length of plane straight line can also be satisfied by combining the crossing lines before and after stations or by selecting No. 9 turnout,and so on.
