城市典型高架复合道路交通噪声污染模拟及防治对策

与一般城市道路相比,城市高架复合道路通行能力大、行车速度高、车辆行驶状态复杂,交通噪声污染极为突出。选取深圳市典型的高架复合道路——春风高架和爱国高架进行实地监测,同时运用SoundPLAN软件模拟其噪声污染现状与安装声屏障后的降噪效果。根据监测模拟结果,从合理进行道路规划、装设声屏障和铺设低噪声路面等方面提出高架复合道路噪声污染控制的对策建议。

Modeling and Countermeasures Study on Traffic-Noise Pollution of Urban Elevated Complex Road

In comparison with ordinary urban roads,the elevated complex roads are featured with greater traffic capacity,higher driving speed and more complicated driving condition,therefore the traffic-noise pollution is very prominent.The study has taken two typical elevated complex roads in Shenzhen,Chungeng and Aiguo roads,as examples to carry out field monitoring.Based on the field data,SoundPLAN software was applied to model the status of noise pollution,also the noise reduction effect after the installation of sound barriers.According to the results of modeling,suggestions on noise pollution control of the elevated complex roads were made from the aspects of sensible road planning,installation of sound barrier,and laying of low-noise road surface.
