摘　　要：为了适应复杂的地形条件及城乡规划等要求,铁路线路通常有较多的曲线段,而有些铁路车站需要结合地形条件或城乡发展规划要求而设置在曲线段上。在曲线站的设计中,需要考虑的影响因素较直线站更为复杂,容易遇到工程量增加、养护维修困难等问题。为此,在考虑铁路运输安全和效率等因素的基础上,以技术水平较高且具有代表性的设计标准为背景,分析总结了影响曲线站设计的主要因素,计算得出了设有缓和曲线和不设缓和曲线两种情况下的曲线加宽值,并给出一个简单的实例进行验证。研究结果对于降低曲线站建设的工程量和投资金额,以及改善曲线站运营养护条件等均有一定的设计参考价值。To accommodate complex terrain conditions and urban-rural planning requirements,railway lines often include numerous curved segments,with some railway stations positioned on them according to topography or urban-rural development plans(hereinafter referred to as'curve station').The design of curve stations involves more intricate considerations compared to straight stations,and can encounter challenges such as increased construction volume and maintenance difficulties.Therefore,taking into account factors such as railway transport safety and efficiency,and using technically advanced and representative design standards as background,the key factors influencing curve station design are analyzed and summarized.The research calculates the widening value of curved tracks for both cases with and without transition curves,and provides a simple practical case for verification.The research results hold valuable design reference for reducing construction volume and investment in curve stations,as well as improving operation-maintenance conditions.
