市域(郊)铁路轨道曲线超高设置研究

针对市域(郊)铁路曲线超高相关规范标准不统一、各超高允许值之间优先考虑原则不明确的情况，对其合理设置进行研究。通过对比分析不同规范曲线超高的设置要求及实例分析，提出兼顾《铁路轨道设计规范》及《市域(郊)铁路设计规范》等行业标准的最大及最小设计超高值、一般及困难情况下的欠超高及过超高允许值、超高顺坡率允许值，以及不同超高设计允许值之间的优先考虑原则，为新建市域(郊)铁路的曲线超高设计提供指导，对行业相关标准规范的完善提供参考。

Rail Curve Superelevation Settings of Suburban Railways

This study investigates the reasonable setting of suburban railway curve superelevations in the case of relatedspecifications and standards that are not unified. The principle of prioritizing the allowable values of each superelevation isnot clear. By comparing and analyzing the requirements for curve superelevation settings in different codes and by analyzingexamples, this paper proposes the maximum and minimum values of design superelevation, the general allowable values forunder-superelevation, over-superelevation, and difficult situations, and the allowable values for the superelevation slope ratio,taking into account the Code for Design of Railway Track, Code for Design of Suburban Railway, and other industry standards.The priority of design principles of allowable values for different superelevations is obtained, providing guidance for the settingof curve superelevations for new suburban railways and providing a reference for the improvement of industry-related standards.
