摘要
通过分路段布点法监测青岛市崂山区松岭路交通噪声污染状况,对松岭路直线路段、立交桥路段的噪声产生原因进行解析,探究高楼噪声反射影响以及绿化带噪声防护性,研究小汽车、摩托车及大型车噪声频谱差异,并根据结果提出防治手段。结果表明:小轿车是直线路段噪声污染主要原因,立交桥路段中同车流量时立交桥底噪声最大,地铁通过时噪声值明显增大。绿化带的防护能力与植物种类相关且与植物高度成正比。车辆噪声主要集中在中低频,摩托车2500Hz以上的高频噪声最大。
The traffic noise pollution status of Songling Road,Laoshan District,Qingdao City was monitored by the method of dividing road sections,and the causes of noise in the straight section and the overpass section of Songling Road were analyzed.It explores the impact of noise reflection in high-rise buildings and the protection of noise in greening,studies the differences in noise spectrum of small cars,motorcycles and large cars,and proposes prevention and control methods according to the results.According to the results of the study,preventive measures are proposed.The results show that cars are the main cause of noise pollution in the straight section,the noise at the bottom of the overpass is the largest when the same traffic flow occurs in the overpass section,and the noise value increases significantly when the subway passes.The protective ability of green belts is related to plant species and proportional to plant height.Vehicle noise is mainly concentrated in the middle and low frequencies,and the high frequency noise above 2500Hz of motorcycles is the largest.
