摘　　要：在国家中长期铁路网规划中西安铁路枢纽具有重要的地位。为研究其空间布局优化问题,首先研究枢纽客运布局,缺少衔接南北向高速铁路的主客运站。其次西延高速铁路、西渝高速铁路引入西安铁路枢纽宏观走向方案,综合比较后建议采用城市东侧布线方案,银西高铁与西武高铁也从枢纽东侧连接贯通;再次研究枢纽内主要客运站布局和分工,西安北承担东西向始发和通过动车作业,西安东调整为主客运站,承担南北向的始发和通过动车作业;最后研究南北向高铁引入西安东站后,还应设置引入西安北站、西安站的联络线。结果表明:西安铁路枢纽内各条线路间互连互通、运输效能可以得到有效发挥。Xi’an railway hub plays an important role in the national medium and long term railway network planning. In order to study the optimization of its spatial layout, this paper studies passenger transportation layout of the hub and the missing of main passenger stations connecting the north-south high-speed railways, and addresses the macro route scheme to introduce Xi’an to Yan’an High-speed Railway and Xi’an to Chongqing High-speed Railway into Xi’an railway hub. The comprehensive comparison recommends the urban east side routing scheme, which also allows Yinchuan to Xi’an High-speed Railway and Xi’an to Wuhan High-speed Railway to be connected from the east side of the hub. Then this paper studies the layouts and work allocations of main passenger stations in the hub: Xi’an North Station undertakes the motor car operation of departure and passing by in the east-west direction, Xi’an East Station undertakes the operation in north-south direction. Finally, this paper focuses on the set up of tie lines to connect Xi’an North Station and Xi’an Station after the introduction of the north-south high-speed railway into Xi’an East Station The results show that the interconnection of various lines within Xi’an railway hub can effectively improve traffic efficiency.
