A Study of Fire Safety Assessment for Road Tunnel in Taiwan

Published:  12 April, 2010

In Taiwan, approximately two thirds of the terrain is mountainous. To promote economic development in rural areas, long road tunnels have been built and a new expressway project is planning to be built. The new expressway project includes nine tunnels (tunnel group) connected by bridges, six of which are longer than 3km, and the longest of which is about 10km. Fire safety management for the tunnel group is much more difficult and complex than that for a single long road tunnel. This work presents a fire safety assessment protocol for an existing tunnel and a new tunnel in Taiwan based on a literature reviews, experts consultations and Computational Fluid Dynamics (CFD) simulation. The existing Hsuehshan Tunnel and a new tunnel group, the East Coast Expressway Tunnels, were selected as a case study in this research. The findings of this study provide a model for assessing whether appropriate fire safety facilities are installed in the existing and new tunnels in Taiwan.
