摘要
探讨了声屏障的声学设计、结构设计、强度设计方法 ,介绍了新型城市高架公路声屏障的试验室测试结果和应用情况 ,这种声屏障平均吸声系数为 0 7,平均隔音量为 30dB ,是控制城市高架公路噪声的有效设施 。
The methods of sound design,structure design and intensification design for noise barrier are discussed,and the Lab trial outcome and application of this new-type of city aerial road noise barrier is introduced.Average coefficient of this noise barrier is 0.7,barrier capacity is 30 dB and comes out to be an efficient measure to control the city aerial noise, which has been used in Shanghai external-round road successfully.
