Abstract
Fires are among the most dangerous incidents in road tunnels that can cause large damages to property and environment and threaten tunnel users. In this paper, the impact of tunnel slope on smoke spread is studied using three 900 m long tunnels with different slopes. The spread of smoke produced by fires of various heat release rates is modelled using Fire Dynamics Simulator. The impact of slope on smoke back-layering is illustrated as well. The simulation results indicate that the slope can have significant impact on the smoke spread in the tunnel.
