沈阳一号线地铁噪声的分析与控制措施

Influence of and Countermeasures Against Noise Pollution of Shenyang Subway Line 1

地铁对周围环境的噪声影响越来越引起人们的关注.采用现场实测的方法,检测了沈阳一号线地铁列车运行时车厢内、站台上以及地铁站外环境噪声最大值.结果表明,除站外环境对乘客影响较小外,各个时间段的噪音均明显超过国家城市四类环境噪声标准(70分贝)的10%～15%.并进一步分析了噪声的主要来源,提出合理有效的控制措施,为后续的沈阳地铁建设提供一定的参考.

The noise pollution of subway is more and more concerned by the people.In this study,we explored the maximal of environmental noise inside of the train,on the platform and outside the subway station when the train is operating.In addition to environment outside the station had less impact on the passengers,the noise of each period was obviously more than four national urban environmental noise standards of 70 dB.Further analysis suggested the main source of the noise pollution of subway and the rationalization proposals for noise control were put forward in the paper,which would be benefit to the following program of Shenyang subway.
