Abstract：Research purposes: The resistance and discharge fume is the major and difficult part in the tunnel design. The rational design for the resistance and discharge fume system is in connecting with the tunnel design success-fail and the people's lives and property. Take the lengthy submarine tunnel for example, this paper studies how to choose rational design for the resistance and discharge fume system and provides referrenc for other tunnel designs.
Research conclusions: According to the tunnel's road net, resistance and recovery facilities' layout, traffic conation, ventilation system,this paper analyzes the fire probability in the different regions and the accepted extent of loss and absorbs the concept of performance fire control design. The transverse ventilation was adopted in the important fire resistance position and the comprehensive discharge fume scheme on the base of longitudinal ventilation in the general position. The resistance and discharge fume theory of civil architecture was taken in the tunnel's resistance and discharge fume design, and the tunnel's resistance and discharge fume theory was perfected. By analyzing the service tunnel, air flow and personal dispersal, the service tunnel's positive pressure design was cancelled to make the tunnel's resistance and discharge fume scheme on economic technique more proper and feasible.
