津蓟线增二线引入蓟州地区方案研究

Study on Plan of Introducing Second Line of Tianjin-Jizhou Line into Jizhou Area

津蓟线作为枢纽内天津港港口集疏运北部通道的重要组成部分,同时又可以起到疏解北京枢纽通道的作用,对其扩能改造在中长期铁路网中具有重要地位。结合地区铁路总图规划、各线能力适应性、周边环境状况及各站作业分工,对津蓟线双线引入蓟州地区重点研究了3个方案,经过多方面综合比较后推荐投资适度、车流组织顺畅且通道能力符合要求的津蓟线方向别引入京哈线段甲岭站方案,对同类设计提供有益的参考。

As an important part of the northern passage of Tianjin Port,Tianjin-Jizhou Line can relieve the passage pressure of Beijing Hub and play an important role in the medium and long-term railway network if expanded and reconstructed.Based on the regional railway master plan,the adaptability of each line,the surrounding environment,and the station division of labor,three plans for introducing the second line of Tianjin-Jizhou Line into Jizhou area were studied.After a comprehensive comparison in many aspects,it is recommended that Jialing Station on Beijing-Harbin Railway should be introduced into Tianjin-Jizhou Line with moderate investment,smooth car flow organization,and suitable passage capacity,which is suitable for similar designs.
