【摘要】：近几年,汽车数量随着社会经济的高速发展也呈持续上涨的趋势,然而,随之而来的众多负面影响也逐渐危害着环境与人类的身心健康。在众多影响中,道路拥堵与噪声污染尤为严重。目前,国内道路建设部门已将主要精力投放于为满足道路交通量而进行的道路建设与规划,而在国外,噪声是与道路交通量是具有相同级别的管控对象。路面噪声是以车辆所发出的噪声为主,其和普通噪声不同之处是其噪声发源是不断行驶的车辆,并发展成具有随机性的噪声,涉及范围广并且危害性具大。鉴于以上原因,本文从实际应用角度出发,通过试验方法,探寻道路噪声产生的原因及控制措施,其研究内容如下:车辆速度与噪声的关系,选择南京市浦口区东华路作为测试路段,为双方向的四车道,宽24米,采用控制经过法测试,车速采用公式计算得到,可以获得车速。记录车辆经过时的噪声值,探讨车速与对应噪声的关系。车流量与噪声的关系,测量所选路段为南京浦口大道,该路段位于浦口区,是新城区主要道路,浦口大道是双方向八车道,具有较稳定的车流量。选择非机动车道和人行道间为测量点,间隔2小时进行一次测量,得到车流量所对应的噪声级别,记录对应车流量下的噪声值,通过试验探讨车流量与车辆速度的关系。道路宽度与噪声的关系,本次测量位置选择在浦口大道,由于地铁施工,半幅封堵,双向八车道变为了四车道通行,道路宽度变为原来宽度的一半,分A、B两个测试点测量不同宽度下的数据,对比分析两点的数据,探讨路面宽度对噪声的影响。路面结构影响与噪声的产生的关系,选择AC-13、AC-20、SMA-13、水泥混凝土路面5中常用路面,采用控制经过法测量60km/h、80km/h下对应的噪声值,比较不同路面相同车速下噪声值,探讨不同类型的路面结构与噪声的关系。本篇论文基于路面噪声来源以及影响因素作为论文选题进行研究,从而提出相应的降低噪声办法和措施,以及相关防治手段,并开展了系统性的论述。
[Abstract]:In recent years, with the rapid development of social economy, the number of cars has been increasing. However, many negative effects have been gradually harmful to the environment and the physical and mental health of human beings. Among the many impacts, road congestion and noise pollution are especially serious. At present, the domestic road construction department has focused on the road construction and planning to meet the road traffic volume, and in foreign countries, noise is the same level of control object as the road traffic volume. Road noise is the main noise emitted by the vehicle, which is different from ordinary noise in that the noise originates from the moving vehicle, and develops into random noise, which involves a wide range and has great harmfulness. In view of the above reasons, this paper explores the causes and control measures of road noise from the point of view of practical application. The research contents are as follows: the relationship between vehicle speed and noise, Donghua Road, Pukou District, Nanjing is selected as the test section, which is four lanes and 24 meters wide. The speed can be obtained by using the method of control test and formula calculation. The noise value of passing vehicle is recorded and the relationship between vehicle speed and corresponding noise is discussed. The relationship between traffic flow and noise, the selected section of the survey is Pukou Avenue, Nanjing, which is located in Pukou District, is the main road in the new urban area, and Pukou Avenue is eight lanes to both sides, with a relatively stable traffic flow. The non-motorized lane and sidewalk are selected as the measuring points. The noise level corresponding to the traffic flow is obtained by measuring every 2 hours. The noise value corresponding to the vehicle flow is recorded and the relationship between the vehicle flow and the vehicle speed is discussed through experiments. For the relationship between road width and noise, the location of the survey was chosen at Pukou Avenue. Due to the construction of the subway, half of the block was blocked, the two-way eight lanes were turned into four lanes, and the width of the road became half of the original width. The data under different widths are measured at two test points of Agna B, and the influence of road width on noise is discussed by comparing and analyzing the data of two points. The relationship between the influence of pavement structure and the generation of noise, select the common pavement of AC-13,AC-20,SMA-13, cement concrete pavement 5, measure the corresponding noise value at 60km / h / h 80 km / h by the method of control pass, compare the noise value of different pavement at the same speed. The relationship between different types of pavement structure and noise is discussed. Based on the research of road noise sources and influencing factors, this paper puts forward the corresponding methods and measures to reduce noise, as well as related prevention measures, and carries out a systematic discussion.
