| 摘 要： | 通过对杭州市典型高架复合道路交通噪声监测，研究高架复合道路交通噪声的时空分布规律。结果表明，噪声与车流量、车辆类型及车速密切相关；噪声随着与高架路距离的增大，地面各测点的噪声值呈递减趋势；高架复合道路平直段与下坡路段的噪声在临街建筑竖直立面的分布规律基本一致，但在不同高度的影响程度上存在一定差异。

| Abstract: | Thespace-time distribution ofthetraffic noiseofelevated highwayswasobtainedin Hangzhou byenvironmental monitoring. Theresultsofspace-time distribution showedthetraffic noise wasassociated withtraffic flow,typesofvehicle and speed ofvehicle. The ground noiseofthe measuringpointdecreased withincreasing distancefrom theelevated highways. The verticaldistribution ruleofflatroadswassimilarto sloperoads, but the noise differed from differentheight. |
