Study on Fire Smoke Control of Underground Annular Channel
Aiming at the characteristics of many crossroads and large slope of ground exits in Suzhou Underground Annular Channel, fire resistant shutters were advised to set as flexible compartment. The whole channel was divided into 6 smoke control sections by fire resistant shutters and exits and ventilation shafts. The schemes of smoke control and people evacuation were presented. Smoke flow in 6 fire scenes was simulated by FDS 4.0. The results show that fire smoke could be discharged to ground along planned route to ensure the safe evacuation of people and cars, and show that the smoke control schemes are reasonable and effective.
