中文摘要：

通过对上海城市轨道交通和部分提速线路的轨面短波不平顺进行现场实测,在对测试数据进行平稳性检验的基础上进一步分析了轨面短波不平顺的幅值分布特性,采用BS EN ISO3095对轨面平顺度进行了分析和评价。研究表明,轨面短波不平顺幅值总体上满足显著性水平为0.05的平稳性检验要求,轨道交通1号线、2号线、3号线及沪宁线和沪昆线焊接接头区的轨面平顺度分别较ISO3095限值高出25.3,21.7,22.2,17.8,10.2 dB,轨道交通3号线、沪宁线及沪昆线的非接头区的轨面平顺度与ISO3095限值的差值分别为10.8,-4.2,-8.3 dB,城市轨道交通轨面不平顺状态劣于提速线路,相同线路条件下焊接接头区的轨面状态要差于非接头区。

英文摘要：

Spot test of rail surface short-wave irregularity in Shanghai rail transit and speed-increasing line is con-ducted.The amplitude distribution characteristics of rail surface shortwave irregularity analysis are analyzed based on stability test.Roughness of rail surface is analyzed and evaluated using BS EN ISO3095.The results show that rail surface shortwave irregularity meets the stability test requirement of significance level 0.05.Regularity in joint area of Metro Line 1,Metro Line 2,Metro Line 3t,he Huning Line and Hukun Line is 25.32,1.72,2.21,7.8 dba,nd 10.2 dB higher than the ISO3095 limit respectively.Difference value between ISO3095 limit and non-joint area of Rail Transit Line 3,Huning Line and Hukun Line is 10.8-,4.2 and-8.3 dB.Rail surface roughness in rail transit is worse than that in speed-increasing linesa,nd the state of rail surface in joint area is worse than that in non-joint area.
