| 摘 要： | 通过对座落于深圳市罗湖区的4条主要高架桥、立交桥周围声环境的24h连续监测发现:高架桥的噪声变化趋势与一般干道类似,其最大值出现在离桥面10～15 m的楼层,而立交桥的纵向噪声总体变化不大;对于临路第1排建筑物的高层部分(10楼以上),由于其纳声范围较广,相对而言,桥上的交通噪声对其贡献较小.因此,高架桥、立交桥噪声污染防治应以规划为主,并根据实际情况,采取设置声屏障和隔声窗相结合进行防护.

| Abstract: | Through 24-hour continuous monitoring of the traffic noise of 4 viaducts and overpasses in Luohu District,Shenzhen City,it is found that the Leq value of the viaducts changes like the normal main roads,and the maximum value appears at 10～15 m over the surface of the viaducts;the Leq value of overpasses does not change a lot.For the high part(over 10 floors) of the fist-line buildings besides the roads,the noise contribution from viaduct or overpass traffic is not major.The noise prevention and control must be based on actual circumstances,and jointly apply noise barriers and windows for sound insulation.Above all,a good planning is very important. |
