| Abstract: | With Shuijian Hill Tunnel as the engineering background,using the FLUENT software,the article conducted the numerical simulation analysis on the diffusion and crossflow-ing of pollution air on left right holes of the tunnel with different wind inlet/exhaust velocity and different distance,and proposed some engineering and technical measures,such as the staggered tunnel exit,construction of mid partitio and construction of ventilation transverse hole to reduce the pollution air crossflowing in close-distance tunnels. |
