In order to study the tunnel fire smoke temperature field, velocity field, changes, this paper proposes a mathe—matical model and a physical model to describe the smoke flow in the tunnel.with the Baizhishan Highroad Tunnel in Chongqing as the research object, On the basis of the proposed models and by using the CFD software, the fire smoke flow in longitudinal ventilation condition is numerically simulated. Some references for the fire control ing,passenger rescue and evacuation are final y provided.
