摘要
为评价温岭市东环高架道路交通噪声的环境影响,采用实测法对东环高架附近代表性点位及不同时间段进行噪声监测,记录等效连续A声级(Leq),以及同步监测车流量、车型等相关数据。根据《声环境质量标准》(GB 3096-2008),由所得监测数据,推测其交通噪声空间分布规律。结果表明,噪声最大值发生于上下班高峰期,交通噪声则随距离的增加而衰减,而道路两侧高层建筑交通噪声随着高度的增加先由小变大后变小。此外,还为该高架道路交通噪声的防治提供一定的参考依据。
The paper was designed to evaluate the impact of road traffic noise in east ring elevated road of Wenling city.Measurements were taken by monitoring the noise of representative points and different time,and then making records of equivalent continuous noise level( Leq),monitoring of traffic volume,vehicle types and other related data. According to'Environmental Quality Standard For Noise'( GB 3096- 2008),the monitoring data suggested that the spatial distribution of traffic noise. The results showed that the maximum noise happened in rush hour,traffic noise attenuated with the increase of distance. With the increase of height road traffic noise of the high- rise buildings on both sides first become large then become smaller. This paper provided some references the prevention and treatment of elevated road traffic noise.
