TRANSFORMABLE SYSTEMS FOR INCREASING EVACUATION PERIOD AND MINIMIZATION OF DAMAGING FACTORS OF FIRES IN ROAD TUNNELS: The above project was fulfilled by financial support of the Georgian National Science Foundation (Grant AR-19-1936))

Abstract

Fires in road tunnels to this day remain a high-risk factor and are still the subject  of  intensive  engineering  research.  For  existing  and  under  construction automobile tunnels in Georgia, the total number of which in the near future will be more than fifty, the only risk factor is a fire. Not looking at the modern methods of designing underground tunnels, which aims to maximize the consideration of fire risk  factors,  the  problem  remains  unresolved  for  the  existing  network  of  road tunnels, to which great attention and financial resources are directed [1, 2]. After the powerful fires that have occurred in developed western countries, the European Union  pays  special  attention  to  the  Trans-European  Network,  which  is  a  top priority for the safety of existing and under construction tunnels.
