Study on Feasibility of Automatic Sprinkler System Applied in Underground Tunnel

For realizing the characteristics of underground fire and the actuality of fire protection facilities, and putting forwards the advice, we should set automatic sprinkler systems in underground tunnels. In this paper, the smoke development and the temperature distribution was simulated using field model (FDS). And the comparisons between the two cases were made. From the results we can see that setting automatic sprinkler systems in underground tunnels has both advantages and disadvantages. But considering synthetically it is feasible.
