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。
Usually, there are many orbits in the railway station area, the sound sources are widely distributed, and the noise barriers of the conventional height can not achieve the noise reduction effect. Therefore, the sound barrier in the station area breaks through the conventional sound barrier of the railway in the form of height and structure. The article introduces the design essentials of the sound barrier of the station from two aspects of acoustic design and structural design, and also puts forward some suggestions on the noise reduction measures of the high speed railway station.
