摘要
作者根据多年研究和工作经验,从声学性能要求、吸声屏布置位置、屏障高度、屏障长度以及材质与设计要求等角度对声屏障的设计与布置原则进行了阐述。在此基础上,针对上海市不同城市道路的噪声特点及周围环境特点,通过几个实际案例,对不同道路及环境条件下的声屏障设计方法、应用实效进行了分析。同时通过对人口密集的城市交通干线两侧土地利用集约化与全封闭声屏障投资费用进行了对比分析,提出未来进行全封闭声屏障设计的建议,并用实例进行了经济环境可行性分析。
After working in traffic noise control for several years, Author has descn＇bed the noise barriers design and layout principles from the acoustic requirements, such as the location-height-length of noise barrier, as well as the materials and design requirements. With this understanding, Author has given several examples for different road noise characteristics and the surrounding environment in shanghai, and analyzes the different noise barrier＇s design and effectiveness. At the same time, after comparative analysis of the investment costs between full-closed noise barrier and the land-use on both sides of the urban traffic road, author has offered proposals of the full-closed noise barrier design, and made the economic feasibility analysis for examples.
