城市轨道交通市郊线特点与线路技术参数研讨

针对我国城市轨道交通市郊线建设发展形式和日前尚无市郊线相应技术标准及设计规范可循的现状,介绍了城市轨道交通市郊线的基本功能,车站设置原则和线路敷设方式.讨论了城市轨道交通市郊线线路特点.着重对线路平、纵断面主要技术参数进行研讨,结合<铁路线路设计规范>和<地铁设计规范>对列车速度目标值的设定,曲线超高及限值和最小曲线半径等提出建议性意见.

Features of Technical Parameters of UMT in Suburban Areas

This paper explains the construction and development situation of Chinese urban mass transit (UMT) in suburban areas,but there has no corresponding technical standards and designing specifications up to now. With an analysis of the technical standards and criterion, the station spacing principles and the laying out form of suburban line,the authors argue that the suburban line shall supply long-distance services;the station distribution can- not be arranged excessively dense and the suburban line shall main...
