摘要:随着社会的发展,交通噪声已成为城区中危害最大、数量最多的噪声源。在主线道路设置声屏障已经成为道路噪声治理工程重要的技术手段,但是由于在声屏障设置中有时会因为现场条件复杂可能无法设置,因此可视现场实际情况考虑围墙声屏障方案。以某别墅为例,介绍围墙声屏障设计。在对别墅噪声情况调查的基础上,利用Cadna/A软件完成声屏障的声学设计工作,从面确定声屏障的设置位置及高度。在满足声学要求的基础上,进一步开展了声屏障结构与构造设计等。声屏障峻工后,现场监测及民众反应其效果良好,获得了一定的社会效益。

Abstract:; With the development of the society, traffic noise has become the most hazardous and most common noise sources in urban area. Sound barriers have become the important traffic noise control facility along the main roads, However, in some other places there may not be appropriate conditions for building that kind of sound barriers The sound barrier wall is an alter native choice, This paper introduces the design of a sound barrier wall in a villa area, On the basis of the investigation of noise sources in the Villa, an acoustic design is carried out with the help of the software Cadna/A, and the locations and heights of the sound barriers are determined. The structure and configuration are designed according to the acoustic requirements. The data from noise monitoring and the public response after completion of the sound barrier wall indicate that the design have good effectiveness, The structure satisfies the residents of the villa area.
Key words: noise; sound barrier wall; acoustic design; structural design; noise reduction 0引言
随着城市交通的日益发展和汽车保有量的迅速增长,交通噪声污染也日趋严重。群众投诉不断增加。降低道路交通噪声污染的途径主要有汽车噪声源的治理,路面的改善,声屏障的使用、住宅隔声窗等手段。对于道路交通噪声治理,声屏障由于其简单、实用、可行、有效、一次性投资小,成为目前被普遍使用的降低道路交通噪声对道路两侧区域局部环境污染的噪声污染防治措施。
根据声屏障降噪原理,若要取得最好的降噪效果,一方面使屏障尽量靠近声源,一方面尽量靠近敏感目标。目前声屏障设置常见于设置在主线路基一侧或者桥梁防撞墩上,对于城市区域快速路的声屏障设置,主
