L’évolution des approches de la maîtrise des risques dans les infrastructures souterraines

Abstract : In the 90's, INERIS very quickly came to the conclusion that a fragmented approach to risks using sub-systems was not sufficient to ensure a good level of preparedness of safety and security in underground infrastructures. Based on this consideration, INERIS has developed a full set of research topics that has led to a global risk management approach. In 1990, INERIS developed completely new software known as NewVendis© allowing a global and dynamic simulation of accident risks in underground infrastructures. As a result, since 2000 complete safety assessments of infrastructures have been possible, taking into account ventilation and propagation of smoke, vehicle movements and the behaviour of hazardous sources such as fire and toxic substances. These results have directly contributed to the French methodology for Specific Hazard Studies for road tunnels that was set up in 2001. These developments are also applicable in rail tunnels, metros, underground storage sites, etc. Since 1997, INERIS has completed its research by studying the human factors in underground safety. In particular, the behaviours of road and rail tunnel users, operators and emergency services were studied during the UPTUN project. This allowed INERIS to carry out a full systemic and global approach to risks considering a combinaison of technical, human and organisational factors. For example, it is now possible to assess the safety margin offered with emergency exits, taking into account important aspects of evacuation procedures and rescue plans. Research is now being carried out in specific fields of new hazards, such as terrorist acts, brought about by society changes. Nowadays, besides this research, INERIS is involved in the L-surF project that will result, in 2008, in the emergence of a new European organisation to increase the efficiency of the European Research Area in the field of underground safety and security. An important objective is the re-organisation of large-scale European experimental R&D programmes and facilities to support a performance-based approach to the risk management.
