摘要：

The investigations on ventilation in tunnel most focuses on straight tunnels. Now bifurcated tunnel has been used widely in metropolis. To confirm the air distribution ratio of bifurcated tunnels ventilation, the numerical simulation of a bifurcated tunnel is conducted in this paper. The air distribution ratio between main tunnel and ramp is concluded that the ratio is about 45% and 55%. Instead of the number of traffic flow and the speed of vehicles, it's the area ratio of main tunnel to ramp that is the main influencing factor.
