Abstract

Procédé de commande d'un groupe de ventilation longitudinale de galerie ou tunnel pouvant être le siège d'un tirage naturel de grandeur variable dans un sens ou dans l'autre par suite de l'effet global résultant de divers paramètres tels que certains facteurs météorologiques ou le pistonnement engendré par le trafic de véhicules dans le tunnel. On inverse systématiquement le sens de refoulement du groupe de ventilation dont le régime demeure le même et on note, par exemple à l'aide d'anémomètres placés judicieusement dans le tunnel, le sens de refoulement pour lequel la vitesse du courant d'air dans le tunnel est la plus grande, et l'on choisit le sens durable de fonctionnement du groupe de ventilation en adoptant le sens essayé qui correspond à la plus grande vitesse du courant d'air. Application à la ventilation longitudinale d'un tunnel routier à double sens.
