Summary:The aim of this study is to investigate the Influence of fire curtain on smoke exhaust effect of Longitudinal ventilation and shaft smoke exhaust combination mode, combined with the actual project established a scale physical model of 1:3, and analyzed the smoke exhaust effect of longitudinal ventilation and vertical shaft smoke exhaust combination mode, measured the fire heat release rate, smoke spread, the temperature inside the tunnel. The results show that the tunnel fire, Longitudinal ventilation and shaft smoke exhaust combination mode has a certain effect to control of flue gas, open fire curtain, the flue gas is controlled to a certain range, there is conducive to better gas discharge tunnel, can provide protection for traffic safety.
