The tunnel, the stations and specific parts of the stations are designed according to different time-temperature curves. Within the tunnel there is no fully developed fire to be expected due to the fact that the metro will not come to a standstill in the tunnel itself, based on the safe haven principle described above. Based on Computational Fluid Dynamics modelling it has been determined that, for this specific project, the NSL curve applies for the tunnel sections.
A realistic worst case scenario of a fully developed metro fire has been applied to model the expected thermal attack on the concrete structure in the stations. The demarcated areas which are directly impinged by flames are designed according to a 120 minute EUREKA time-temperature curve. The areas which are not directly exposed to flame contact are designed to withstand ISO-834 time-temperature curves for 90 or 120 minutes, depending on the fire load found in the CFD modelling.
