【摘要】 本文介绍了城市隧道废气排放的几种方式及各自特点,指出了传统高风塔的选址与城市景观规划及工程拆迁存在的矛盾,着重探讨了低风井废气排放技术及局部敞口自然通风排放技术,同时指出用于城市隧道废气排放的传统环评方法尚存在缺陷,提出一种基于城市地理信息系统的CFD仿真环评方式,为了从根本上解决隧道废气排放的环境问题,采用隧道废气净化技术将是今后解决隧道废气排放问题的发展趋势。更多还原

【Abstract】 This paper introduced several kinds of city tunnel exhaust fashions and corresponding characteristics,and pointed out the contradictions between traditional tall exhaust tower site with city planning and construction demolition.Because of the drawback of traditional environmental assessment methods,a new environmental assessment method based on city geographic information system and computational fluid dynamics was brought up.To solve the environment problem of tunnel exhaust fundamentally,it is a tendency that waste gas should be purified before exhausted.更多还原
