Abstract:

In this paper, the Pathfinder software was used for numerical simulation to analyze the influence of different settings of the underground metro operation depot, including safety zone, metal mesh and fire location on personnel evacuation.The results of the study are as follow: the road around the underground metro operation depot should be set as open as possible. The addition of metal expansion network is not conducive to the evacuation of people in the base, and it will not reduce its fire evacuation safety level that the different forms of vehicle bases and the increase in evacuation distance under the cover. In order to ensure the  safety of the vehicle base, it is necessary to prevent the fire near the  safety exit of the parking inspection library under the cover.

Key words:  , fire safety, the underground metro operation depot, evacuation of personnel, security
