摘要
对杭州市高架快速路两侧的典型建筑群进行了噪声监测,结果表明第一排/列敏感点噪声等效声级均超出4a类标准,昼间超标0.2—5.6dB,夜间超标8.3~15.9dB;第二排/列的噪声等效声级均超出2类标准,昼间超标0.9-5.7dB,夜间超标2.2~8.3dB。典型建筑群的第一排/列对第二排/列的隔声及距离衰减效果为5.1~14.9dB。对交通噪声的防治,可采取设置合理噪声防护距离、建设低噪声路面、设置隔声屏障、建筑物噪声防护和加强交通噪声管理等措施。
The noise monitoring of typical architectural group are developed along elevated express highway in Hang Zhou city. The measures of prevention and control of traffic noise are proposed, including setting up of rational noise prevention distance, low noise road surface construction, erecting of sound insulation screen and strengthening traffic noise management.
