城际铁路速度目标值选择分析

Analysis on the Selection of Speed Target Value of Intercity Rail Transit

城际铁路是介于高速客运专线与城市轨道交通之间的一种新型轨道交通模式,在其运输组织模式、技术标准的选择上有其自身的特点。在城际铁路的主要技术标准中列车速度目标值是一项重要的技术指标,它直接影响项目的工程投资、运营效益。因此,结合项目的实际情况,合理确定标准显得尤为重要。文章根据广佛东环广州南至竹料段的具体情况结合项目的客流特点及功能定位、速度目标值与车站分布的匹配关系、本项目与相邻路网的协调性等方面,对项目的速度目标值进行了全面分析比较,最终确定本项目采用160 km/h的速度目标值。

As a new type of rail transit different from high-speed rail passenger special hne anti urban rail transit,intercity rail transit has its own characteristics in the transport organization mode and the selection of technical standards.It is extremely important to determine the standard of the project as the actual situation of the project for the train speedtarget value is an important technical index in the main technical standard of the intercity rail transit which directlyaffects the project investment and operational efficiency. In this paper, the speed target value of the project is analyzedand compared according to the specific situation of the Guangzhou South-Zhuliao section of Guangzhou-Foshan EastRing, and combining with the passenger flow characteristics, the function orientation of the project, the matchingrelationship between the speed target value and the station distribution, the coordination of the project and the adjacentroad network, the speed target value of 160km/h is determined in the project ultimately.
