上海城市外环线大型声屏障设计与实践

以上海外环线交通噪声治理工程为背景，在现场踏勘和专业技术经济论证的基础上，详细研究了大型声屏障声学设计、材料结构设计、基础设计等关键技术问题，预测了实施声屏障的降噪效果，并对工程实践中产生的一系列问题提出了相应的对策。通过工程实践及实际降噪效果监测分析，预测值和实测值基本相符，说明新型声屏障的设计思路及方法是正确的，采用该声屏障是治理城市交通主干线交通噪声比较好的选择。

Large Scale Noise Barrier Design for Shanghai Outer Ring and Its Practice

Some key technical issues such as the acoustic design,material structure design and foundation design of large scale noise barrier are studies in detail for the harness project of traffic noise along the Outer Ring of Shanghai,based on site survey and tecnical economy assessment.The effectiveness of reducing noise by implement of noise barriers is predicted,for the relevant problems creating in its engineering practice some corresponding countermeasures are put forth.The real measured data of noise reductio...
