摘要:: 环线+射线模式是常见的轨道交通线网结构，目前大型平原城市铁路枢纽也逐渐形成了环线+射线格局的铁路路网结构。其中环线线路作为枢纽中的切向连接部分，其功能的优劣决定了枢纽效率的高低。而环线与射线之间交叉点的设置方式决定了客流交通的质量和效率，对环线功能具有决定性的作用。铁路受其站场形式、运营特征、建设代价等的影响，线路交叉点设置形式相比其他轨道交通更为复杂多样。本文以规划的成都外环铁路为例，探讨铁路枢纽内环线-射线交叉点的设置形式。

Abstract:: The "loop + radial route" mode is a common rail transit network structure. At present, the railway network structure with the "loop + radial route" pattern has been gradually formed for railway terminals in large plain cities. The loop route is the tangential connection part of a terminal, and its function determines the efficiency of the terminal. The setting of the intersection between the loop and the radial route determines the quality and efficiency of passenger traffic, and plays a decisive role in the function of the loop. Compared with other rail transit systems, the intersection between two railway lines sees more complicated because of the various types of station yards, complex operating systems, and high costs of construction. Taking the planned outer loop railway in Chengdu for example, this paper discusses the settings of the intersection between loop and radial route within railway terminals.
