市域铁路速度目标值研究

摘要

Urban regional railway is a new transportation mode, and some of its features, including the line's length, the distance between stations, and the speed target value, usually fall in between urban rail transit and intercity express railway. Moreover, in some cities or regions, the differences among urban regional railway, urban rail transit and intercity express railway have become blurred more and more. Especially, an urban regional railway itself may be a part of an intercity express railway, at the same time maintaining the function of an urban rail transit. So the research on the speed target value is particularly important. Because there is no special design code for the design of urban regional railway, this paper, taking the under-construction railway from Dongsheng to Erdos Airport as an example, analyzed the speed target value suitable for this project in detail.%市域铁路是一种新型运输模式，其线路长度、站间距、速度目标值等均介于城市轨道交通和快速铁路之间。在某些城市、某些地段，市域铁路与城市轨道交通、快速铁路之间的区别变得模糊。市域铁路本身就可能是快速铁路的一段，同时又具有城市轨道交通功能，所以其速度目标值的研究尤为重要。鉴于目前还没有专门的适用市域铁路的设计规范，以在建的东胜至鄂尔多斯机场铁路为例，具体分析适宜本项目的速度目标值。
