国内外铁路用钢轨标准对比分析研究

Comparative Analysis and Research on Railway Rail Standards at Home and Abroad

选取国内外铁路用典型钢轨标准TB/T 2344-2012 《43kg/m-75kg/m钢轨订货技术条件》、 TB/T3276-2011 《高速铁路用钢轨》、 BS EN 13674-1:2011 《Railway applications-Track-Rail Part1:Vignole railway rails 46kg/m and above》、 ISO 5003-2016 《适用于46 kg/m及以上的传统或高速铁路用平底钢轨》和JIS E 1101-2001 《热轧平底钢轨及道岔用特殊断面钢轨》(2006年和2012年进行了局部补充修订)进行对比研究,分析标准中技术要求存在的差异及其可能造成的安全性影响。通过研究结果可得,较欧洲、日本和国际ISO标准,我国高速铁路用钢轨标准在技术要求上已经达到了世界一流水平,部分测试项目及要求较国外标准更为全面和严格。

In this paper, the typical railway rail standards used at home and aboard( TB/T 2344-2012 、 TB/T3276-2011 、 BS EN 13674-1 : 2011 、 ISO 5003-2016 and JIS E 1101-2001) are selected to compare and analyze their differences on the technical requirements and the potential security influences. According to the research results,compared with the European, Japanese standard and the ISO standard, the TB/T 2344-2012 and TB/T 3276-2011 rail standards for high-speed railway in China have reached the world first-class level in terms of technical requirements,and some test items and requirements are more comprehensive and strict than the foreign standards.
