屏蔽门对地铁站内环境影响的实验研究

为改善目前地铁车站普遍存在的温度偏高、活塞风和噪声问题,徐家汇地铁站进行了安装屏蔽门系统的改造。本文通过对安装屏蔽门前后长期的温湿度测试和噪声检测,研究了屏蔽门系统对改善地铁站内环境质量的作用。实验结果表明屏蔽门系统可有效降低夏季地铁站台和站厅的温度和噪声,有效提高地铁站的舒适性。本文的实验结果和结论也为以后地铁车站的建设和改造提供了现实依据和参考。

Experimental Research on Effect of Platform Screen Door on Indoor Environment of Subway Station

There are many problems in subway station,such as the increased temperature,piston wind,noise,etc.Platform Screen Doors(PSD) was fixed up in Xujiahui subway station to improve the indoor environment quality.In this paper,the parameters including temperature,relative humidity and noise were measured before and after the PSDs being fixed to investigate the effect of PSDs on the indoor environment quality of subway stations.The results indicated that the temperature and relative humidity of station office and platform could be obviously decreased with PSDs,as well as the noise.The conclusions would be helpful for the later construction and retrofit of subway station.
