摘要
近十年来上海在城市高架道路两侧建造了30多公里的声屏障,但对于它们的降噪实效则缺乏了解和总结。根据我们的一些噪声测量结果和主观反应调查来看,其中存在问题不少,而且大部分声屏障所起作用极为有限。因此,作者认为有些基本设计概念需要澄清,同进对一些有效措施进行了探讨。
： Around 30 km sound barriers alongside the elevated roadway have been built in Shanghai during past decade, but their noise abatement effectiveness is still a question. Some noise measurements and subjective response surveys show that restricted shielding ac- tion of these barriers can, in many cases, be produced. Therefore, the author wishes to clar- ify some fundamental design principles in practice and some design guidelines for effectively screening off the traffic noise at elevated roadway are also discussed in this paper.
