文章以奎先隧道内燃机车通过时气体中的有害成分为监测对象。考察了奎先隧道及周边的气象条件,重点监测了不同工况下,内燃机牵引客车、货车排出的污染物含量并分析了造成污染物积累的成因。结果表明：在内燃机车经过奎先隧道时,NOX的含量在10.2-59.2 mg/m3范围内,是背景值的17倍;CO的含量在11.3-26.8 mg/m3范围内,是背景值的10倍;TSP的含量在14.1-25.2 mg/m3范围内,是背景值的7倍;各类有害成分均在监测点4达到峰值。同时,针对奎先隧道的自然条件,文章提出了一些改善的措施。

In the paper,the harmful gas was the monitoring objict which the internal combustion engines engendered through KuiXian tunnel.Under different working conditions,the pollutant contents which Internal combustion engine traction buses and vans exhausted were studied emphatically.The reason was analysed which caused accumulation of pollutants.The results show that internal when combustion engine go through KuiXian tunnel,the content of NOXin 10.2-59.2 mg/m3,within the scope of the background value is 17 times;the content of CO in 11.3-26.8 mg/m3,within the scope of the background value is 10 times;The content of TSP in 14.1-25.2 mg/m3,within the scope of the background value is 7 times.All kinds of harmful components reach peak value at the forth monitoring station.At the same time,with the natural conditions in KuiXian tunnel,the paper puts forward some improvement measures.
