佛莞城际铁路长隆站平面优化设计研究

Study on Layout Optimization Design of Changlong Station

为了在满足长隆地下站运输需求的基础上,尽量缩小车站规模,降低工程投资,从整个珠三角城际网的交路设置、车站折返能力、折返线有效长度等主要技术参数入手,分析长隆站在整条线路及整个城际线网中的功能定位和对整个线网的灵活性、适应性的影响,对长隆站平面布置进行多方案技术经济比选,并通过对折返线有效长进行优化特殊设计,即列控系统采用虚拟一定线路长度数据的方法,推荐的车站布置满足长隆站折返能力的需求,并大大降低车站规模,节省工程投资。

In order to meet the needs of the Changlong station's traffic demand and minimize the station's scale and engineering investment,the paper analyses the station's functional orientation and the influence on the flexibility and adaptability of the whole Pearl River Delta's intercity railway network and main technical parameters,such as the locomotive routing,the station turn-back capacity,length of the back line are studied. Then the station layout optimization design and the technical and economic comparison of multiple layouts are conducted. In addition,through the optimization of the effective length of the turnback line by means of virtual line length for train control system,layout of the station is recommended to meet the needs of the Changlong station's transportation demand,and also to reduce the scale of the station and project investment.
