摘　　要：钢轨焊接接头是无缝线路的重要组成部分,其平直度情况对于列车行车速度、运行平稳性和旅客乘坐舒适性具有重要影响。采用型尺测量方法,对某线路现场新铺钢轨焊接接头平直度进行了测量、统计及分析,结果表明现役钢轨焊接接头平直度与TB/T1632-2005《钢轨焊接》关于平直度的要求差距很大。结合轨道平顺性控制特点,总结了钢轨焊接接头平直度控制的主要措施,对钢轨焊接接头平直度研究方向提出了建议,指出全面系统研究钢轨焊接接头平直度,对于发展我国高速重载无缝线路、加快经济建设等具有重要意义。The flatness of the weld joint has an important effects on the speed and the stability of seamless railway,as well as the comfortable feel of the passengers.Through the measurement of a railway line by steel rule,and then compare its data to the 《the the Railway welding》 standard（TB/T1632.1-2005）, the results is di^tisfacfion that the pwsent flames of the railway can＇t meet the requirements of the standard.Therefore, on the basis of the smoothness control properties and the flatness control methods of the railway, the paper showed the direction of the study on it,and pointed out that all-around systematizing the flatness has an important significance on the development of the high-speed over-loading seamless way in the future.
