高速公路沿线植物声屏障设计与应用研究

Study on Design and Application of Plant Acoustic Barrier along Highway

对高速公路交通噪声特性和治污降噪机理进行分析,阐述了利用植物声屏障降低高速公路沿线交通噪声的可行性和优越性,介绍了植物声屏障的设计模型与设计方法,以及植物选择原则及范围。在此基础上,以云南楚大高速公路K37+100～K37+250段为例,对植物声屏障设计应用进行实例研究,分析了试验项目概况、设计方案,并提出了其中的注意事项,结合大量统计资料分析和云南楚大高速公路植物降噪试验项目的研究,以期为类似工程项目的实施提供参考。

Through analysis on characteristic of highway traffic noise and pollution-treating and noise-reducing mechanism, the paper had il- lustrated feasibility and advantage to reduce traffic noise along highway by making use of plant acoustic barrier, introduced design model and methods of plant acoustic barrier, and principles and scope for plants＇ selection. On this basis, by taking K37 ＋ 100 -K37 ＋ 250 section of Yunnan Chuda Highway for example, application of plant acoustic barrier had been studied, general situation and design schemes of pilot pro- ject analyzed, and some matters needing attention proposed. Based on the analysis of a large amount of statistical data and researches on pilot project of noise-reducing by plants along Yunnan Chuda Highway, it hoped to provide reference for similar enzineering Droiects.
