摘要 以上海市5条隧道为研究对象,采用车载移动监测的方式监测记录各条隧道沿程颗粒物(PM_(2.5)和PM_(10))的质量浓度,结合隧道自身特点,探究隧道内部颗粒物分布规律和成因。结果表明:隧道内颗粒物质量浓度分布主要与隧道自身的通风方式、结构特点和通过的车辆及其形成的活塞风有关。通过平行比较5条隧道的通风效果,发现翔殷路隧道通风效果较好,人民路隧道北线污染较为严重。 This paper investigated the PM_2.5 and PM_10 spatial distribution regularities and ventilation effect in five tunnels in Shanghai. A mobile monitoring was accomplished, and the result indicated that the ventilation measurement, construction features and the piston airflow caused by vehicles mainly determined the ventilation effect in tunnel. Comparing the air quality in five tunnels, Xiangyin Road Tunnel acted the best, while Renmin Road Tunnel acted the worst.
