从降噪角度看隧道内路面结构的选择

Pavement Structure chosing of tunnel from noise viewpoint

通过实测的水泥路面与沥青混凝土路面噪声的对比,以及低噪音路面与水泥路面的吸声系数的对比,并结合各个路面的综合性能,分析了隧道内路面结构的选择,并且指出SMA路面结构更适合隧道路面。

Tunnel pavement chosing was analyzed from measured noise of portland cement concrete pavement and asphalt pavement and sound absorption index of low noise pavement and portland cement concrete pavement. Integrate performance analysis was also used. The results in dicate that SMA pavement structure is more suitbale to tunnel pavement.
