The results show that the higher the wind velocity is, the faster the concentration of the pollutants will attenuate after the pollutants leave the tunnel portal; while the transversal wind will result in the higher concentration of pollutants in a large

计算结果表明，风速越高，废气离开峒口后，浓度衰减得越快；而横向风则会导致隧道两侧很大区域内的污染物浓度超标。
