Research on Smoke Spread in Qililong Navigation Tunnel

摘要

Based on the tunnel in the second line of Qililong Sea Route on Fuchun River, combined with the shipping case in the navigation tunnel, the paper discussed the ship fire. Three fire scenarios were set for the tunnel: cruisers fire, cargo ship fire and oil tanker fire. How to set the fire power for fire scenarios was discussed in the paper. And the fire processes of these three scenarios were simulated. The law of smoke spread as well distribution and variation condition of visibility was obtained under different fire scenarios in navigation tunnel. The vault temperature of tunnel in fire was discussed too, and the ventilating measures were given to protect the lining structure in tunnel.
