太焦高铁长治南站周边路网竖向设计研究

Analysis on Vertical Design of Road Network around Changzhi South Station of Taiyuan-Jiaozuo High-speed Railway

针对山区城市边缘地带沟壑纵横、地形高差大的特点,以太焦高铁长治南站为例,提出了山区高铁站周边路网竖向设计的原则及思路。提出山区高铁站周边路网竖向设计应综合考虑现状地形、高铁站选址、高铁站与路网的衔接,以及交通组织、排水流向、管线覆土、土方平衡等各个方面要求,采取交互反馈设计的形式,最终实现路网竖向设计高程的经济、安全、合理,同时保证进出站客流能够快速、安全、多路径实现交通转换。

Aiming at the characteristics of the criss-cross ravine and gullies,and large terrain elevation difference in the edge zone of mountainous city,taking Changzhi South Station of Taiyuan-Jiaozuo High-speed Railway as an example,the principles and ideas of vertical design of road network around high-speed railway station in mountainous areas are put forward.The current terrain,site selection of high-speed railway station,connection between high-speed railway station and road network,traffic organization,drainage direction,pipeline soil covering,earthwork balance and other requirements should be considered in the vertical design of road network around the high-speed railway station.And the form of interactive feedback design is adopted.Finally,the vertical design elevation of the road network is economical,safe and reasonable,and at the same time the passenger flow in and out of the station can be fast,safe and multi-path to realize the traffic conversion.
