摘要：

The train operation causes a piston effect which generates train-induced wind affects the ventilation volume of the natural ventilation system. This study measured the wind velocity and the concentration of particulate matter (PM) in natural ventilation. In addition, the volume of natural ventilation at subway vent shift and the mass of inflow and outflow PM by train operation were calculated. As a result of the study, the volume of inflow ventilation from urban to subway tunnel is higher than the volume of outflow ventilation. However, the concentration of PM10 and PM2.5 in subway tunnel is about 1.7 to 2.6 times higher than the concentration in the city. Consequently, the mass of PM10 and PM2.5 is emitted from the subway tunnel and affect urban air quality.
