Cadna/A在立交桥噪声预测评价中的应用
Application of Cadna/A Software in Prediction and Assessment of Expressway Noise
【摘要】 Cadna/A是基于德国RLS90通用计算模型的噪声模拟软件,其计算原理源于标准ISO 9613-2∶1996"户外声传播的衰减的计算方法",广泛用于环境评价、建筑设计、交通管理、城市规划等众多领域。采用德国Datakustik公司出品的Cadna/A软件,模拟预测了新建立交桥交通噪声对周围环境的影响,并提出了噪声污染的控制措施。
【Abstract】 Computer Aided Noise Abatement(Cadna/A) is a noise simulation software based on Germany calculation model of RLS90.It is widely applied in environmental assessment,construction designing,traffic management,city planning etc.By utilizing the Cadna/A designed by Germany company,Datakustik,the influence of traffic noise on environment are simulated and predicted with a view to provide countermeasure of noise pollution.
