Abstract

Fire safety in tunnels is one of the most important parts of their design. Inadequate design assumptions may lead to significant life and property loss and severe damage to the tunnel construction. This paper presents an impact analysis of the selected input parameters on the outcomes of a computer fire model relating to fire severity, tenability and exposure of construction. Variability and uncertainty of the design fire size and wind speed are examined in the Fire Dynamics Simulator and compared to the results of a real-scale tunnel fire test. The results of the presented model cases underline the importance of the evaluated input parameters in relation to evacuation, construction damage and rescue operations.
