公路隧道能见度及其关联影响因子研究

Study on Visibility in Highway Tunnels and its Relevant Influencing Factors

通过对谭裕沟隧道和梧桐山隧道内能见度、机动车流量和构成、主要空气污染物的监测和研究 ,探讨了隧道内能见度下降的主要原因 ,结果表明 。

Based on the study and monitoring of visibility,vehicle flow rate,vehicle compositions and major air pollutants in Tanyugou highway tunnel and Wutongshan highway tunnel,the major causes of the decrease of visibility in highway tunnels were discussed in detail.Results show that major pollutant that influences visibility is fine particles with smaller diameters.
