Reliability analysis of the fire protection lining in the high speed train tunnel 'Groene Hart'
conference paper
Sprayed fire protection linings in bored, high speed train tunnels are a new field of application. Questions were raised on the failure probability of the lining during the service life of the Groene Hart tunnel. The fire protection lining is reinforced with a wire mesh fixed to the tunnel lining. A systematic failure analysis has been carried out to identify possibly causes and growth mechanisms of delaminations of the protection lining. The research shows how the reliability of a new system can be analysed. The analysis uses standard reliability methods, and a combination of analytical and numerical modelling, small and full-size experiments and expert judgments. The conclusion is that sprayed fire protection linings can be applied in the high speed Groene Hart train tunnel for short service periods. For long service periods an additional inspection regime has to be-established.
