Smoke Control in Typical Fire Scenes of Underground Complex Traffic Tunnel

摘要

According to the characteristics of one complex traffic tunnel in Guangzhou, and according to Froude similarity theory, a solid model with geometric dimension ratio of 1:3 is established. This paper introduced the spreading characteristics of smoke when the longitudinal ventilation and point smoke extraction were working together at the same time. And the best smoke control scheme was put forward for smoke control in different smoke prevention zones of this tunnel.
