| 摘 要： | 隧道出口污染空气窜流易被相邻的隧道进口吸人形成二次污染,恶化相邻隧道内的运营环境.以k-ε方程三维紊流模型及多组分扩散传输方程为物理计算模型,采用FLUENT流体计算软件模拟了中梁山隧道在不同自然风条件下洞口废气的扩散情况,得出该隧道对另一隧道入口的影响程度.提出了以树林替代挡壁来减少二次污染的建议. |
| 关 键 词： | FLUENT软件 窜流 二次污染 挡壁 |

| Abstract: | Secondary pollution caused by inhalation of polluted air at the exit of the tunnel deteriorates the environment of the adjacent tunnel.Based on the k-εthree-dimensional turbulence model and multi-component diffusion transport equation,the spread of gas at the extrance of Zhongliangshan Tunnel was simulated by the Fluent software;the influence degree on another tunnel entrance was analyzed as well.Finally,applying forests instead of retaining wall to reducing secondary pollution was proposed. |
| Keywords: | FLUENT Software flow channeling secondary pollution retaining wall |
