摘要
用根据交通噪声传播规律和声学原理研制开发的《城市道路立交隔声屏障设计系统》对三义庙立交隔声屏障进行声学设计,并从隔声屏障的结构安全、对行车的影响、耐久性能、易施工性以及与周围环境协调等几方面进行研究分析。实测和运营现测表明,降噪效果明显,达到了设计要求。该系统的研制为我国城市道路立交隔声屏障的设计提供了先进的科学方法和手段。
A system of noise barrier design was developed, which provides a means for predicting traffic noise, defining the geometric configuration of a barrier to produce a desired noise reduction, and also provides a noise reduction evaluation for building noise barrier. A sample project of noise barrier in San Yi Miao interchange was built in 1994. Through test and measure in site,it was proved that San Yi Miao noise barrier can reduce traffic noise 5-10dB(A),and also proved that the whole project is of safety and easy installation.
