摘要: 市域快速轨道交通系统制式比选是项目前期研究的基础内容,直接决定项目的设计标准和投 资。在综合整理中国市域快速轨道交通设计案例的基础上,明确系统制式的选择标准:速度目标 值、车辆选型、供电系统、工程经济性。分析比较不同制式在各个标准下的性能特性及优劣,从工 程造价角度分别说明不同制式在土建工程费用、车辆购置费、车辆基地投资、运营成本等方面的区 别。研究表明,120 km·h-1速度目标值的直流1 500 V市域B型车,投资规模适中,车辆技术成熟, 运营维护成本较低,性价比较高。

Abstract: Comparing different metropolitan rapid rail transit systems is the basic step in a project initial preliminary research, which directly dictates the design standards and project investment. By reviewing the design cases of metropolitan rapid rail transit in China, this paper clarifies the system selection criteria in the targeted travel speed, vehicle type selection, power supply systems, and project economic analysis. Through comparing the performance and characteristics of different systems under various criteria, the paper analyzes the differences among systems in several aspects: construction costs, vehicle purchase costs, vehicle facility investment, system operating costs, and etc. The results show that the 1,500 VDC metropolitan vehicle B with 120 kilometers per hour targeted speed has a moderate investment scale, reliable vehicle technologies, low operating and maintenance costs, and a high ratio of quality to cost.
