초록
PM10 which has been accumulated in the subway tunnel spreads to the platform and concourse, thereby aggravating air quality of the underground station. By ingredients analysis of PM10 in the tunnel, it found that the main ingredient of PM10 is Iron(Fe) which is caused by the friction between rail and wheel as the train is running. Especially, this study shows that the wear progress of the high rail at the curve is affecting on the distribution of fine dust in the tunnel.
