| 摘 要： | 以江苏省内部分高速公路路侧绿化带为对象,通过分析绿化带结构对交通噪声衰减的效果,重点探讨了高速公路高路基及缓坡路段与路堑路段绿化降噪林带的设计方法。研究结果表明,在不同立地条件下,降噪林带设计也不同,一般来说,填方路段林带结构以混合林带为主,挖方路段以纯林带为主。

| Abstract: | Taking the greenbelt of highways in Jiangsu provinc as examples,this paper analyzes the effects of greenbelt structure on traffic noise reduction,expecially the effect of design method of noise reducing greenbelt on the highway subgrade,gentle slope road and road cutting section. The study points out that there is a great difference in noise reduction effect with the variation of forest belts. The belt design varies under different conditions,mixed forest belt is suitable for filling section while pure belt is suitable for slope section. |
