Advances in Optimum Ventilation Control for Road Tunnels
Abstract: Major improvements in road-tunnel safety could be implemented within the first decade of this century. The few years immediately following the large fires in the Mont Blanc (1999), Tauern (1999) and St. Gotthard (2001) mainly focused on technology and organization. New technologies were developed for a rapidly growing market and new equipment was installed. Concurrently, the necessary...

Best Practices and Perspectives for Cross Connections in Twin-Tube Rail Tunnels
Abstract: Cross connections represent a fundamental safety facility for rail tunnels. The key parameters characterizing cross connections, including maximum distance, minimum dimensions, technical equipment and level of protection, depend on a number of regulations and vary significantly from country to country. For this reason, a research study was initiated by Amberg Engineering Ltd. in cooperation...

Complex ventilation of the Brenner Base Tunnel during construction
Abstract: The present paper documents design of ventilation and cooling during tunnel construction of the lot H41 Sillschlucht-Pfons of the -66km long Brenner Base Tunnel, between Austria and Italy. Challenging requirements result from the fact that the tunnel connects two countries with different regulations, from the extreme complexity of the construction site and from a number of interactions with...

Ventilation of Rail Tunnels – State-of-the-Art and Trends
Abstract: New rail tunnels are very frequently equipped with emergency ventilation systems, while the vast majority of existing tunnels are still naturally ventilated. This paper reviews the technical and historical reasons, which led to this situation and illustrates the major issues to be accounted for while assessing the need for a ventilation system for a rail tunnel. The main requirements to be...
