基于Cadna/A软件的山区高速公路声环境影响预测——以开阳至瓮安高速为例

山区高速公路的噪声预测受周边地形影响比较明显。研究以开阳至瓮安高速为例,在Cadna/A软件的噪声计算模式基础上,将山区地形资料集成并建立噪声预测模型,对高速周边噪声敏感点的声环境质量进行预测,为敏感点采取更为合理的声环境保护措施提供依据。

Noise prediction of motorway in mountainous area is obviously affected by surrounding terrain.The study take the motorway from Kaiyang toWenan as an example,based on the noise calculation model of Cadna/A software,import the mountain terrain data into the software and build Noise prediction model,predict the sound environmental quality of sensitive points around the motorway.Furthermore,the basis of more reasonable sound environmental protection measures was provided.
