Compared with operated tunnel, one of the distinguishing features of a tunnel during construction is its single-ended geometry. The direction of fire smoke movement is the same as the direction for worker to evacuate the tunnel. This paper calculates fire-induced conditions, including temperature, smoke movement and visibility, which are influenced by two different ventilation systems. According to the simulation, when the fire located at bottom of tunnel, forced extraction is more effective; when the fire located at middle of tunnel, forced injection can protect workers in tunnel. Besides,increasing ventilation rate can control smoke spread effectively.
