Abstract:
In order to give design basis for the super long highway tunnel, based on fluid dynamics, the tunnel ventilation system was converted to the ventilation network with the graph theory and method. The ventilation network was solved with the ventilation calculation software. According to the design standards of highway tunnel ventilation and lighting, the required air of different conditions in the about line of Mixiliang tunnel was calculated to determine a reasonable number of ventilation equipment and installation location. In the ventilation solver, the traffic pressure was fitted as cubic polynomial with the ventilation volume, and joined into the network as an axial flow fan. The results show that the tunnel ventilation design can meet the tunnel ventilation requirements, at the same time, the feasibility and applicability of the advantages of node method for network ventilation is demonstrated. The left lane of traffic in the recent ventilation air pressure decreases rapidly with the reduction of traffic speed, the proportion of the traffic pressure in the total pressure is between 5.94% to 28.37%. 9 tabs, 1 fig, 7 refs.
