城际铁路引入城市的方式探讨

Study on Way of Introducing Intercity Railway into Cities

城际铁路引入城市会面临许多困难和制约因素,如何充分利用城市有限的土地资源及既有铁路资源布设城际铁路,值得深入研究和探讨。文章对城际铁路引入城市的站址选择、引入方式和车场布置形式进行了初步研究,分析了不同引入方式的优缺点。城际铁路引入城市方式的决定因素是客运站站址,站址的选择优先考虑引入既有主要客运站或辅助客运站,次之为其他条件好的车站或独立新建。城际铁路按其引入城市内的线路走向和既有铁路的关系,可采用并行、并线、分线引入3种方案,按线路的空间形态有平面、高架、地下3种方式。车场布置有贯通式和尽端式两大类,根据具体情况选用;引入既有客运站可采用分场或共场布置,新建车场有地面、地下、高架3种方式选择。

Intercity railway introduced into the city will face many difficulties and constraints. How to make full use of the limited land resources in the city and the existing railway resources is worthy of further study and discussion. In this paper, site selection, ways of introduction and yard layout form for the intercity railway introduced into city are prelimi- narily studied. The advantages and disadvantages of different ways of introduction are analyzed as well. The passenger station site is the decisive factor of introducing way of intercity railway into the city. The priority of station site selection should be given to the main passenger station or auxiliary passenger station, the other better conditioned stations or inde- pendent new stations come second. According to the line trend of intercity railway introduced into city and relation be- tween existing railways , three introduction ways like parallel, doubling, branching can be adopted; According to space form of the lines, three ways including plane, elevatedand underground can be used. The yard layout is divided into through type and end type, which shall be selected based on the concrete condition; The introduced existing passenger station can be arranged with partial field or co-field layout. The new yard has three options including ground, under- ground and elevated.
