铁路客车联络线纵断面技术标准的研究

Research on Technical Standard for Route Profile of Railway Passenger Train Connection Line

目前我国的铁路线从运输性质上基本可分为客运专线、客货共线和货运专线铁路。适应于客运专线的技术标准是以运行动车组来确定其基本设计参数的,适应于客货共线的技术标准是以运行机车牵引车组来确定其基本设计参数的,货运专线铁路设计参照了客货共线铁路的技术标准,对于机车牵引客车车列的联络线技术标准没有做出相应的规定。结合现行《铁路线路设计规范》(GB50090—2006)和西宁站改造及相关工程的实践对客车联络线纵断面技术标准进行探讨。

In term of transport property, railway lines in our country at present can be divided into passenger dedicated line, mixed passenger and freight line, freight dedicated line. Essential design parameters in the technical standard suitable for passenger dedicated line is based on the need for the operation of electric multiple unit; Essential design parameters in the technical standard suitable for mixed passenger and freight railway is based on the need for the operation of locomotive traction; The design of freight dedicated line usually cites the technical standard used in mixed passenger and freight railway as a reference. But, there is nothing about the technical standard which should be suitable for the connection line running passenger train by locomotive traction. For this reason, combined with the current Code for design of Railway Route, and combined with the renovation project of Xining Railway Station and its relevant projects, the technical standard which will suitable for the route profile of passenger train connection line is discussed in this paper.
