轨道交通市域线越行站配线设计研究

Study of Siding Design in Overtaking Station on Urban Railway

轨道交通市域线快慢车运营模式在国内尚无运营实例,越行站配线设计也无设计标准。通过对轨道交通市域线越行站的行车功能、越行速度、配线道岔等分析,确定越行站的配线形式;结合越行线安全防护距离和安全线有效长度的计算分析,研究地下单岛、地下双岛、高架侧式、高架双岛4种常见越行站形式的越行线配线设计,为快慢车运营模式的市域线越行站配线优化设计提供参考。

Up to now there is not any precedent of operating express/slow trains on urban railways in China, nor is there a domestic design standard for siding design in overtaking station. By analyzing the function of operation, speed of overtaking and switches, forms of the siding in overtaking station were determined. By referring to the calculation and analysis of safety distance of hair line and effective length of the security line, design of the overtaking line of four common forms in overtaking station, i.e., underground single island, underground double islands, elevated side, elevated double islands, was studied. The research could be a reference for design optimization of siding of a overtaking station of urban railway lines with express /slow train operation mode.
