Five large-scale fire tests, including one pool fire test and four HGV mock-up fire tests, were carried out in the Runehamar tunnel in Norway in year 2003. Detailed information about these tests is presented. In addition, previous work on these tests and new analyses are presented in this report. Heat release rate, fire growth rate, gas temperature, flame length, radiation, fire spread, gas production, ventilation, backside wall temperature, pulsation, backlayering and visibility are investigated thoroughly. Simple theoretical models are developed to estimate and predict these parameters. The correlations developed can be used by engineers working on fire safety in tunnels.
