Highway tunnel afford convenient traffic to people,which also brought many new issues to the prevention of fire.This paper presents three-dimensional numerical simulation with the method of CDF to development of the form of hot current behavior when fired in the Long and Large highway tunnel,regarding the single-hole and one-way tunnel as a research object in Qinling.The computational domain of this tunnel is the 200 m in length,the 65.37 m~2 in cross-sectional area,the 10.5 m in total width and the 7.2 m in total height.Fire center is located at 100m from the tunnel entrance.This research carries out the distribution of the concentration filed and velocity filed during the different condition of ventilation.It provides a reference for designing the plan of ventilation and the method of preventing fire scientifically.
