高速公路声屏障设计与降噪效果评估研究
Study on highway sound barrier design and noise reduction effect evaluation
随着社会经济的快速发展和城市化进程的加速,高速公路建设规模不断扩大,极大地促进区域间的经济联系和人员流动。高速公路的快速发展也带来日益严重的噪声污染问题,对沿线居民生活质量和健康产生了不良影响。声屏障作为降低道路噪声污染的有效手段之一,其通过隔声和吸声两种方式,对车辆运行中产生的噪声进行反射、吸收及衍射,从而阻隔噪声的传播并降低敏感点的声压。声屏障以其显著的降噪效果、灵活的安装方式、节约土地资源以及较强的环境适应性,在国内外得到了广泛应用。在高速公路的噪声控制中,声屏障的设计与优化,有利于提升降噪效果。本文结合高速公路噪声产生机理,分析声屏障结构设计原则,探讨高速公路声屏障设计与降噪效果。
With the rapid development of social economy and the acceleration of urbanization process, the scale of expressway construction is constantly expanding, which greatly promotes the economic connection and personnel flow between regions.In the noise control of expressway, the design and optimization of sound barrier are conducive to improving the noise reduction effect. This paper analyzes the design principle of the structure of acoustic barrier and discusses the design and noise reduction effect of expressway.
