高速铁路客站线间距确定分析

Analysis of the Parameters Related to Determining the Midway between Tracks in High-speed Railway Passenger Station

研究目的:车站线间距是铁路站场设计的主要技术参数之一。时速200 km及以上高速铁路(客运专线)在设计规范中只给出了确定车站线间距的方法,没有给出最终的参数,而站场设计必须有详细准确的数据。本文结合设计实践,对高速铁路(客运专线)的车站线间距进行了总结、分析,以给出参考意见。研究结论:线间距除了与线间是否设置接触网立柱、隔声屏障、雨棚柱等设施有关外,还与高架站房结构柱、防撞墙、线间纵向排水槽的设置等因素有关,本文对有立柱的正线与到发线间、无立柱的正线与到发线间、到发线与到发线间等分别给出数据。

Research purposes： The midway between tracks in station is one main technical parameters of station design. The design method is stipulated in the Design Code for the midway between tracks in station of the 200 km/h high - speed railway or above （passenger dedicated line ） , but the final parameters needed in the station design are not stipulated in the Design Code. This paper analyzes the parameters related to determining the midway between tracks in station of high- speed railway （passenger dedicated line） and offers the reference opinions on it based on the design practice. Research conclusions：The midway between tracks in station is not only related to the facilities of catenary post, noise ban-let and canopy column, but also related to the facilities of the structural column of elevated station building, anti - collision wall and longitudinal drainage between tracks. This paper gives data about midway between main line and receiving -departure tracks with or without column, and the midway between receiving -departure tracks respectively.
