Abstract: Safe evacuation risk gradually increases with the increase of buried depth of metro stations. We analyze the impact of station structure, evacuation safe zone, evacuation facilities, passenger flow volume and evacuation guidance on passenger evacuation time of deeply buried metro stations. We also construct a network model and an evacuation model of deeply buried metro stations for emergency evacuation scenario. We eventually employ urban rail transit passenger evacuation simulation system to calculate passenger evacuation time of a deeply buried metro station through model validation, taking a Beijing constructing deeply buried metro station as a case.Simulation result is compared with theoretically calculated evacuation time. Results show that all passengers can be evacuated to security areas from platforms within 5 minutes, consistent with relevant regulations. The simulation system can therefore be applied to the research of evacuation time of deeply buried metro stations.

Key words: urban rail transit, deeply buried metro station, simulation, evacuation time, evacuation calculation
