西安地铁站与新建铁路北客站的结合设计研究

Research on Intergrated Design of the Subway Station and the New North Railway Station of Xi'an

研究目的:为提高综合交通枢纽的整体换乘效率和功能空间的安全舒适性,需研究各种交通工具的换乘关系,进而避免相互隔离的各种空间、复杂的指示系统和漫长的步行距离。其中如何结合整体规划,综合交通枢纽一体化设计、同步实施,合理布置地铁站位,达到快速疏散超大客流,是综合交通枢纽设计研究中的关键问题。研究结论:(1)西安北客站与地铁的综合设计从规划布局、站位选择、流线组织和结构适应性等方面进行分析,介绍了一体化组织实施遇到的问题及取得的经验;(2)西安北客站采用"建桥合一"的结构模式,融合地上建筑、桥涵和地铁结构三种结构形式,地铁和铁路枢纽的整体结合,可满足大型旅客集散场所大跨度、大空间的使用要求;(3)总结出多种设计布局模式,对各类综合交通枢纽设计具有参考价值。

Research purposes： In order to improve the overall transfer efficiency and function space security comfort of the integrated transport hub,the various transportation transfer relationships need to be studied,to avoid the various separated space,the complex indicating system and the long walking distance. How to combine the overall planning,achieve the design and synchronous implementation and integrated transport hub,reasonable arrangement of the location about the subway stations,to achieve rapid evacuation of large passenger flow,which is a key problem in the design of integrated transport hub. Research conclusions：（ 1） The integrated design of Xi＇an North railway station and subway station is analyzed from the planning,organization, location choosing and structure adaptability, the problems and experiences of integration organization and implementation are introduced.（ 2） Xi＇ an North railway station uses the model of the ＂ the unity of buildings and bridges ＂,fuses three kinds of structure form of building on the ground,bridges and subway structure.Combination of the whole subway and railway hub satisfies the requirement of long span and large space in the big passenger distribution place.（ 3） A variety of layout patterns are summarized,and have the reference value for all types of integrated transport hub design.
