摘要
在详细调查沪杭高速公路嘉善张家浜中桥路段(试验路段)未建道路声屏障前噪声情况的基础上,介绍了试验路段工程概况及道路声屏障的设计,并分析了声屏障的现场降噪效果。试验路段声屏障的声学指标达到预期目标,具有良好的环境效益。
On the basis of noise pollution investigation before
sound barrier has set up at test section——Zhangjiabang
bridge at Jiashan section of Huhang highway, design of sound barrier at test section was introduced in this paper.Result of sound reduction of the barrier has been analyzed. In conclusion, acoustic characteristics of the sound barrier has achieved expected goal, and also brought positive environmental benefit.
