高速公路复合型路基金属结构声屏障施工关键技术

Key Technologies for the Construction of Metal Structure Sound Barriers in Composite Roadbeds of Highways

为减少公路两侧噪音,提高周围群众的生活质量。声屏障的设计、施工工作,一直是建筑学界研究的重点方向。在过去,我国主要采用玻璃钢声屏障隔绝高速公路上的噪音,但由于该声屏障声学性能、力学性能及耐老化性能不足等问题,已经难以满足时代发展的迫切需求。在这样的时代背景下,金属结构声屏障因其降噪效果好、经久耐用、安装方便受到广泛关注。鉴于此,本文将依托四川天府新区至邛崃高速绿化项目进行复合型声屏障设置研究,即在噪声源与受声点之间插入开白叶孔铝合金吸声板,使声波在传播过程中受到障碍物影响而引起明显的衰减,旨在减少附近居民所在一定区域的噪音影响,希望能够起到一定的参考作用。

In order to reduce noise on both sides of the highway and improve the quality of life of the surrounding residents.The design and construction of sound barriers have always been a key research direction in the field of architecture.In the past,China mainly used fiberglass sound barriers to isolate noise on highways.However,due to the insufficient acoustic,mechanical,and aging resistance of this sound barrier,it has become difficult to meet the urgent needs of the times.In this era,metal structure sound barriers have attracted widespread attention due to their good noise reduction effect,durability,and easy installation.In view of this,this article will rely on the Sichuan Tianfu New Area to Qionglai Expressway Greening Project to conduct research on the installation of composite sound barriers.That is,an open white leaf hole aluminum alloy sound-absorbing plate is inserted between the noise source and the sound receiving point,so that the sound wave is significantly attenuated due to the influence of obstacles during propagation.The aim is to reduce the noise impact of nearby residents in a certain area,hoping to provide some reference.
