地铁车辆段出入线接轨方案探讨

介绍地铁车辆段出入段线的一般配线形式．针对近年来强调在车辆段出入线与正线接轨处应设置安全线问题，提出不同的看法。对照《地铁设计规范》中安全线的设置条件，认为在车辆段出入线与正线接轨点处不需要设置安全线。分析近年来新推出的车辆段出入线接轨方案存在的问题，提出2个优化设计方案，并以上海地铁1号线梅陇车辆段出入线方案进行类比，证明没有安全线列车运行的安全是可以保证的。结果表明，该优化设计方案具有车站长度短、可大幅度降低工程造价、行车安全、调度灵活等优点。

Options for Track Connection with Transfer Tracks of Depot

The authors introduced the general layout of transfer tracks of the depot, and put forward their viewpoints on the practice of setting safety siding at the connection of transfer tracks of the depot with main line tracks in recent years. According to the conditions specified by the Code for Design of Metro , it is not necessary to set the safety siding. The authors analyzed the problems existing in the connection options of depot transfer tracks and present two optimized design options. By contrasting the option without the safety siding with the project of transfer tracks at Meilong depot on Shanghai subway Line 1, it has been proved that safety can be secured without the safety siding. As indicated by practice, the proposed optimized options possess the merits to shorten station length, diminish construction costs to a large extent, and secure safety train operation and flexible traffic dispatch.
