目前在机务折返线平面设计中,依然采用以运行车辆为主的《铁路线路设计规范》进行设计,造成了轨距与其主要运行机车的状态不匹配,使轨距难以保持。鉴于此,在线路平面设计及既有线改造中,要根据实际运行车辆种类,对平面设计标准的拟定原则、计算方法及参数选择方法做适当修订。
At present, in the plane design of repaired return lines, the design of “railway line design specifications” mainly for running vehicles is still used to design, resulting in the gauge mismatch with the status of its main running locomotive, which makes it difficult to maintain the gauge. In view of this, in line graphic design and existing line reconstruction, according to the actual type of vehicle to be driven, the principles, calculation methods and parameter selection methods of graphic design standards should be properly revised.
