| 摘要: |
| 为科学全面地开展城市道路交通噪声影响评估，更精确地服务道路交通噪声污染治理工作，选取南京市具有代表性的道路交通干线，采用手工监测和自动连续监测的方法，进行不同路段噪声污染程度及其随时间、空间变化规律的研究。结果表明，地面快速路段、高架路段以及衔接路段两侧噪声敏感建筑物受道路交通噪声影响较大，夜间均超标；相邻区域要达到2类声环境功能区昼间标准限值要求，需距离地面快速路慢车道约45 m，距离高架路段慢车道约92 m；要达到2类声环境功能区夜间标准限值要求，需距离地面快速路慢车道约175 m，距离高架路段慢车道约172 m；敏感建筑物所受噪声影响随楼层高度升高而增大，同时噪声影响情况与道路两侧建筑物密度、道路车辆行驶速度有关。建议严格道路及噪声敏感建筑物规划控制，采取阻断传声路径、受声建筑物强化保护等措施控制噪声影响。 |

| Abstract: |
| For the purpose of conducting a comprehensive scientific assessment of urban traffic noise impact and serving traffic noise pollution control more accurately， this project selects representative traffic arteries in Nanjing City and conducts a research on the noise pollution level of different road sections and their spatial variation patterns over time. The study shows that noise sensitive buildings on both sides of ground express sections， elevated sections， and connecting sections are greatly affected by road traffic noise， and the noise levels exceed the standard at night. To meet the daytime standard limit requirements for Class 2 acoustic environment functional areas in adjacent areas， it is necessary to be about 45 m away from the ground expressway slow lane and about 92 m away from the elevated section slow lane. To meet the night time standard limit requirements， it is necessary to be about 175 m away from the ground expressway slow lane and about 172 m away from the elevated section slow lane. The noise impact on sensitive buildings increases with the height of the building， and the noise impact is also related to the density of buildings on both sides of the road and the speed of road vehicles. It is suggested that strict planning control of roads and noise sensitive buildings should be implemented， and measures such as blocking sound transmission paths and strengthening the protection of sound sensitive buildings should be taken to control noise impacts. |
