Study on Fire Evacuation and Smoke Spread of Atrium Metro Station

Abstract

In recent years, the construction of subway in China is in a period of an rapid development. The passengers are in high density within the subway during the operation time, the problem of safety in emergencies has attracted more and more attentions. The structure of atrium metro station is special, fire partition area in the station is difficult to divide. And there is a hidden danger of fire, which is not easy to realize effective exhaust and smoke control. Once there is a fire the magnitude of injuries will be overwhelmingly disastrous. Therefore, more attention should be paid on pedestrian’s evacuation in subway stations. Therefore, an atrium subway station in Beijing is selected, hot smoke test and STEPS software simulation were carried out. We also analyzed the escape environment and escape routes, reasonable evacuation time is obtained, as well as a reasonable escape strategy.
