Abstract

People evacuation in tunnel in fire conditions belongs to important tunnel safety problems. In this paper, simulation of fire in a short unidirectional 2-lane road tunnel and its evacuation using the FDS+Evac system are analysed. FDS+Evac enables to simulate fire spread in the tunnel utilizing the obtained fire characteristics for modelling evacuation of people. Three evacuation scenarios which differ from each other by cars location in the tunnel are illustrated. The impact of turned cars on fire spread and people egress is demonstrated. Some specific particularities of the current version of FDS+Evac, which must be taken into account in modelling the egress in tunnel fire conditions to avoid misrepresentation of input representation, are discussed.
