摘要
本文以上海地铁1号线部分地下车站为研究对象,通过调研与实测的方式研究了地铁站内的环境状况。实验结果表明:地铁站台内以温湿度为代表的微气候能够满足乘客的需求。CO2的浓度水平略高于0.10%的标准值,换乘站的浓度比非换乘站的浓度明显高出很多。在地铁站内,颗粒物浓度过高,PM10的平均浓度范围为200~800μg/m3,超标比较严重,晴天的站台内颗粒物浓度普遍高于雨天的站台内颗粒物浓度,特别是细颗粒物PM2.5的浓度所占比例很大。
This paper takes the underground station of Shanghai metro line 1 as the research object and studies the environmental conditions in the subway station through investigation and measurement. The experimental results show that the microclimate represented by temperature and humidity can meet the needs of passengers. The concentration level of CO2 was slightly higher than that of 0.10%, and the concentration of the transfer station was significantly higher than that of the non-transfer station. In metro stations, the particle concentration is too high, the average PM10 concentration range is 200~00 μg/m3, overweight is more serious, sunny platform inside the particle concentration is generally higher than rainy particle concentration in the platform, especially fine particulate matter concentrations of PM2.5 proportion is very big.
