摘要: 为解决城市道路隧道的污染物排放问题,以昆明东外环中路隧道为例,介绍了自然通风在城市道路隧道通风系统中的应用。采用SES4.1模拟软件对有自然通风口时隧道运营通风进行了计算,并采用CFD模拟软件对洞口污染物扩散范围进行了研究。结果表明,在隧道顶部设自然通风口,采用分散排污方式,可减少隧道洞口污染物排放总量,降低洞口污染物扩散范围和通风系统运行费用。该应用成功解决了隧道洞口污染物集中排放对周边环境的影响,为今后类似工程的设计提供了新的思路。

Abstract: The design of the operation ventilation of a highway tunnel in Kunming is studied in the paper. Ventilation solutions with/without natural ventilation intakes are presented, and in the end, natural ventilation solution is adopted for the tunnel. The operation ventilation of the tunnel with natural ventilation intakes, as well as the diffusing range of the pollutants at the tunnel portal are studied by means of SES4.1 and CFD simulation software, and the environment is evaluated. The results show that the emissi on and diffusing of pollutants at the tunnel portals can be brought under effective control if natural ventilation intakes are installed on the top of the tunnel and decentralized emission mode is adopted.
