Abstract
Investigations concerning smoke dispersion in a rail tunnel were
content of a research project which was performed in the already
finished section KAT1 of the Koralmtunnel in Austria. Full scale
tests were performed, covering fires with a max. heat release
rate of up to 21 MW. Smoke dispersion was monitored using
video cameras and related temperature distributions at various
sections of the tunnel were recorded. Focus of the investigation
was the smoke dispersion in the region of the cross passages
where passenger evacuation will happen.
The tests shall provide supporting information for the selection
of the proper escape doors (swinging doors or sliding doors) which will be installed for passenger evacuation via the cross passages. In order to provide sufficiently safe conditions during the self-evacuation phase, smoke shall not restrict the escape possibilities. The tests aimed at investigating the interaction
between fire load, smoke production rate and escape possibilities
as a function of the installed ventilation system and the aforementioned parameters.
