摘　　要：为研究新建城市轨道交通高架站台噪声现状及特点,以及站台工作人员的累积噪声暴露量,选取某线的ZFL站、GML站和HQ站进行了实地测量。从噪声级、频谱和进出站列车时间与声级关系几方面对测量结果进行了分析。结果显示,站台列车进站LAeq值为78d B（A）,出站LAeq值为79d B（A）。无列车通过时背景噪声LAeq值（白天）为66~74d B（A）。倍频程频谱分析得出,站台列车进站出站噪声具有宽频带噪声特征。时间历程分析得出,站台列车进站和出站的平均时间是30s和29s。进站第13s达到最大值LAF max78~89d B（A）。出站第15s达到最大值LAF max82~90d B（A）。站台工作人员白班噪声暴露量为LAeq73d B（A）,夜班噪声暴露量为LAeq72d B（A）。In order to study the noise level and characteristics of a newly built elevated station of urban rail transit,and to know the noise exposure of platform staffs,three platforms of a urban rail transit line,namely ZFL platform,GML platform and HQ platform,were selected and measured. The measured data was analyzed from the aspects of noise level,character of spectrum and relation of noise strength to the time as a train coming into or going out of the station. The results showed that the LAeqvalue is 78 d B（ A） and 79 d B（ A） when train is coming and going. The LAeqis 66 ~ 74 d B（ A） when no train passing through in daytime. The spectrum analysis showed that the platform noise has the feature of wide-bend noise. The time course showed that the average time need 30 seconds and 29 seconds when trains come into or go out of platform. The LAF maxis 78 ~ 89 d B（ A）,when the train comes into the station on 13 thsecond. The LAF maxis 82 ~ 90 d B（ A） when the train goes out of the station on 15 thsecond. The noise exposure LAeqof platform staffs is 73 d B（ A） in day shift and 72 d B（ A） in night shift.
