铁路车站声屏障设计要点

Brief Introduction to Design of Railway Station Noise Barrier

通常铁路站区轨道较多,声源分布较宽,常规高度的声屏障已无法达到其降噪效果。因此站区声屏障在高度及结构形式突破了铁路常规的声屏障。文章从声学设计和结构设计2个方面对车站声屏障的设计要点进行了介绍,同时也对高速铁路车站设置降噪措施提出了一些建议。

Generally, the noise barriers of normal height in a railway station area are no longer to effectively reduce noise with the growth of tracks and wider source of noise, so that the height and formation of station noise barrier have to break through their conventional form. This paper presents a brief introduction to the design of station noise barrier to acoustics and structure, and it also brings forward some suggestions on the noise reduction measures for with regard high-speed railway stations.
