Study on Fire Smoke Movement of Urban Traffic Link Tunnel

Abstract:

Fire simulation software (FDS) was employed to simulate the fire smoke movement of urban traffic link tunnel (UTLT) under the semi-transverse ventilation. Numerical simulation and theoretical analysis were used to analyze the fire smoke movement in three fire scenarios. The analytical results show that: semi-transverse ventilation can effectively control the spread of fire smoke. When the exhaust air rate is certain, the exhaust port interval of 20 m and 50 m has little effect on function of smoke control. The research results provide references for the design of smoke control measures in UTLT.
