Numerical Study on Fire Smoke Preventing and Exhausting of Underground Highway Tunnel
Underground highway is an effective measure to ease the traffic pressure. However, fire in underground highway is of great danger. This work investigated the instantaneous velocity field, gas field and temperature field distribution of the underground highway in case of fire theoretically. The smoke field and temperature field distribution was determined at the safe altitude. The expression of the critical flow velocity in the previous work was verified. The optimal escape time in the fire upstream and downstream is 30s and 90s, respectively. The optimal escape distance in the fire upstream and downstream is 35m and 200m, respectively. The best is to read these instructions and follow the outline of this text.
