Ecology underground transport facilities with different modes of vehicles movement
Volkov A.P. , Sverdlov A.V. , Rykov S.V.
Ventilation and air conditioning tunnels and underground Parking lots are the most important means of livelihood of the person in conditions of high concentration of exhaust gases in the architectural confined space, often having no natural airflow. Therefore, the calculation of emissions of pollutants into such structures and the design of these structures is an important scientific and technical challenge. In the operation of road tunnels, the emission of pollutants into the atmospheric air or from the portal of the tunnel, or from the ventilation shafts. The concentration of contaminants in the outgoing air stream is determined by the length of the tunnel, its cross-section profile of the route, the scheme of ventilation and air amount, intensity and structure of traffic flow, speed of traffic, number of lanes (routes), the directions of movement of vehicles (one-way or two-directional).
