摘要
以无锡-宜兴高速为例,选取沿线典型互通区域,在对Cadna/A软件用于高速公路噪声预测的可行性进行验证的基础上,通过软件对高速公路互通区的不同交通噪声源进行模拟,确定主要噪声源,针对主要噪声源,分析不同高度声屏障的降噪效果,为采取更为合理的声环境保护措施提供依据。
Taking Wuxi-Yixing Expressway as an example,the typical Freeway Interchange is selected.On the basis of verifying the feasibility of Cadna/A software for highway noise prediction,the different traffic noise contributions of the interchange area are simulated through the software.Identify the main noise sources and analyze the noise reduction effects of different height sound barriers against the main noise sources,to provide a basis for taking more reasonable sound environmental protection measures.
