| 摘 要： | 通过对杭州市高架快速路和主次干道两侧敏感建筑群临路第一排/列和第二排/列噪声监测表明,高架道路两侧临路第一排/列和第二排/列敏感建筑昼夜噪声等效声级均超标,主次干道两侧临路第一排/列和第二排/列敏感建筑昼间噪声等效声级基本全部达标,但夜间第一排/列全部超标,夜间第二排/列绝大多数超标。对高架快速路和主次干道两侧不同水平距离处的交通噪声监测表明,昼夜要达到2类声环境标准距离在90~100 m外。建议杭州市交通干线防噪声距离控制为高架和城市快速路红线外不小于50 m,主干道红线外不小于40 m,次干道红线外不小于30 m。通过采用疏水性沥青路面、对高架道路设置隔声屏障、为敏感点安装隔声门窗、加强交通管理等措施,可有效改善道路两侧敏感点室内外声环境质量。

| Abstract: | According to the noise monitoring in the elevated expressway and the sensitive buildings that on both sides of major and minor highway in Hangzhou,it is indicated that the equivalent sound noise level at the first and second row sensitive spot that is on both sides of elevated expressway exceeded the standard level.The day equivalent sound noise level at the first and second row sensitive building basically reached the standard,but at night the equivalent sound noise level at first row sensitive spot totall... |
