【摘要】 对京港澳高速黎托下沉段附近小区的噪声现状进行分析,采用Cadna/A软件建立该路段的噪声预测模型,并预测在该路段设置声屏障后沿线噪声敏感区的声环境质量,对声屏障设置前后的噪声进行监测,分析声屏障的降噪效果,为高速公路沿线交通噪声污染提出控制措施。更多还原

【Abstract】 Through the analysis of traffic noise impact on the nearby communities in the Lito sinking section of the Beijing-Hong Kong-Macau highway, Cadna/A was used to establish a noise prediction model for the road section and predict the acoustic environmental quality in the noise-sensitive area along the road before and after setting the sound barriers. The noise reduction effect of the acoustic barrier was analyzed,and the control measures for traffic noise pollution along the expressway were proposed.更多还原
