Abstract

With the development of infrastructure construction, tunnel construction is becoming more and more. However, the pollution diffusion from adjacent upstream tunnels can cause secondary pollution to downstream openings. The paper used FLUENT to simulate the characteristics of pollutant diffusion. Two forms of adjacent tunnels, single-hole tunnel and double-hole tunnel, were used as the research objects. Also simulate the interporosity flow issue, it is concluded that when the tunnel wind speed is equal, the interporosity flow has nothing to do with the wind speed, but has to do with the distance between upstream and downstream spacing.
