摘要
通过对成绵高速公路上多个噪声敏感区声屏障的实施 ,对声屏障的声学设计、结构设计及景观设计等方面进行了分析探讨。提出了新型声屏障设计的思路。经测试表明 :新型声屏障不仅对敏感区声环境的改善达到了预期效果 ,而且使声屏障由原来单一的障壁形式变成了交通道路上与周围环境融为一体的一道靓丽的风景。
From the design and construction of several noise-barriers nearby sensitive areas of traffic noise along Cheng-Mian expressway,the design principles of a noise-barrier have been analyzed and investigated on the aspects of acoustic considerations,structure and landscape etc.Some new ideas are presented to design new style noise-barrier.By testing,it's shown that these new style noise-barriers,not only improved acoustic environment of sensitive areas but also became a beautiful scenery.
