道路声屏障是控制交通噪声的重要措施,其结构对声屏障降噪效果影响很大。作者对国内声屏障结构形式的现状进行了分析,介绍了国外常见的多重边、T型、Y型等顶部结构的发展情况,同时介绍了声学软表面、平方余数序列表面等新型顶部结构的发展状况。提出我国应该加强隔声屏障顶部结构研究,特别是加强降噪效果较好的T型等声屏障结构的研究,以提高我国声屏障应用水平。
Road noise barrier is an important measure to control traffic noise, and its structure has a great influence on noise barrier noise reduction effect. The author analyzes the current situation of the structure of domestic noise barriers and introduces the development of top structures such as multiple sides, T-shaped and Y-shaped structures in foreign countries. At the same time, the development of new top structures such as acoustic soft surfaces and square residual series surfaces are introduced situation. It is pointed out that China should strengthen the study of the top structure of sound insulation barrier, especially to study the T-type sound barrier structure with better noise reduction effect so as to improve the application level of sound barrier in our country.
