| 摘 要： | 以天津某隧道工程环评为例,介绍了隧道NOX排放量的计算方法;采用高斯模式预测了风塔下风向NO2扩散浓度,计算结果表明在排放口下风向129 m范围内、空间69～73 m高度范围内NO2浓度超标;采用TOP模式预测了峒口下风向NO2的扩散浓度,计算结果表明峒口下风向30 m范围内NO2浓度超标;提出了隧道工程废气污染控制措施。

| Abstract: | Based on a tunnel EIA report in Tianjin,the calculating method of NOX emmision rate in the tunnel was introduced and the dispersion concentration of NO2 was predicted by Gauss model.The result showed that the NO2 concentration would exceed the standard GB3095-1996 within the horizontal range of 129 meters from the stack and leeward between 69 meters and 73 meters high.The dispersion concentration of NO2 was predicted near the tunnel portal with TOP model,the NO2 concentration from the tunnel portal leeward ... |
