[Abstract]:With the gradual increase of domestic automobile ownership and the increasing demand for municipal road infrastructure, municipal roads are gradually developing from plane traffic to three-dimensional traffic mode, and urban viaducts, Overpasses and tunnels are constantly reflected in the construction of municipal roads. Since atmospheric pollutants from municipal roads involved in tunnels form more concentrated sources of emissions at tunnel entrances and vents, which is in sharp contrast to other municipal road pollutant emission modes, therefore, More and more scholars pay more and more attention to the impact of pollutant emission from municipal tunnels. It is of great theoretical and practical significance to study the atmospheric effects of municipal road projects involving tunnels. Taking the Fenghuangshan Tunnel Project in Dazhou City as an example, the distribution of ambient air sensitive points along the project is investigated in this paper, and the source strength of the tunnel mouth is calculated based on the CFD model of fluid dynamics. Based on the prediction and evaluation of the influence of AERMOD model on the atmospheric environment during the tunnel operation period, the corresponding atmospheric prevention measures are put forward and the feasibility of the measures is analyzed. The research results of this paper can be used as reference for the prevention and control of atmospheric pollution during the operation period of Fenghuangshan Tunnel Project in Dazhou City, and also for the atmospheric environmental impact assessment of similar projects. The research shows that the CO concentration in each section of Fenghuangshan Tunnel in Dazhou City has reached the standard requirement of the Design Code for ventilation and Lighting of Highway Tunnel. All sensitive points outside the project tunnel, Phoenix Village and the Lotus Lake area planning area CO,NO2 concentration in the operation of the near, medium, long-term hours, daily average, The annual maximum landing concentration can reach the second level standard in GB3095-2012, and the impact of the project on the regional atmospheric environment is acceptable.
