Advanced studies on the propagation of fire in a motorway tunnel - case history by the test center

摘要

Cofiroute is the largest private motorway operator in France, with responsibility for a motorway network of approximately 900 km in the west of the country. The centerpiece of the A86 in the west of Paris is a tunnel which carries traffic on two storeys. In the event of a fire, this gives rise to a variety of questions regarding the safety of tunnel users and intervention forces as well as the tunnel staff. Extensive tests on the basis of an experimental simulation of a serious accident resulting in a fire are to be used in order to study the propagation of fire between the vehicles in the tunnel, both above and below the seat of the fire.
