Risk analysis to optimise safety during basic tunnel design
conference paper
The risk analysis to select the preferred basic tunnel design for the tunnels in the High Speed Train Link South from Amsterdam to Antwerp is described. The risk analysis has been split up in two stages: a broad qualitative risk analysis and a quantitative risk analysis. The results of the qualitative risk analysis for the 7.2 km bored Green Heart tunnel are presented in this paper. The accident scenarios are identified and the risks are ranked for the selection of major accident scenarios. The risk reduction potential of possible safety measures in a railway tunnel is presented. Based on the risk determining input parameters the risks of the tunnel design alternatives have been ranked for the basic design alternatives without and with additional safety measures. Finally conclusions are drawn with respect to safety level of the three design alternatives.
