摘　　要： 对影响行车环境的隧道噪声进行了调查分析。通过现场测量的大量隧道噪声调查结果,对隧道内噪声的来源及隧道内噪声的特点进行了详细的分析,并对隧道内车内噪声与隧道外车内噪声进行了比较。结果表明,隧道内噪声比隧道外高很多,隧道内车内噪声比隧道外车内噪声也高很多。通过理论公式对隧道内衬吸声材料的降噪效果进行了计算,结果表明,隧道内衬吸声材料可以有效地降低隧道噪声。最后提出了对隧道内路面结构选择的一些建议,尤其是两种低噪声路面OGFC和SMA的选择。 The noise pollution in tunnel was investigated. The source and character of tunnel noise were analyzed, with inside and outside noise of a car in tunnels compared, from tunnel noise investigation results. The results indicated that the noise in side the tunnel is much higher than that outside the tunnel, and the noise inside a car inside the tunnel is much higher than that outside the tunnel. Noise reduction effect of sound absorption materials inside the tunnel was calculated. At last some suggestions on pavement selection in tunne were proposed, especially the selection of two types of low-noise pavement, namely OGFC and SMA.
