Résumé

Based on the modelling and analysis of the CO2 concentration in the tunnels and underground railway with shielding doors, the authors point out that, in winter, with air exhausters on the top of the tracks and at the bottom of the platforms along the railway stations closed and piston air functioning only, the temperature conditions can, but the fresh air can not, be satisfied in the tunnels during morning and evening rush hours. The calculation shows that the least fresh air required in the most unfavourable tunnel during the rush hours is 41 m3/s, which is coincident with the air volume of air exhausters installed on the top of the tracks and at the bottom of the platforms. In conclusion, if shielding doors are installed, the air exhausters must be started up during the rush hours.
