以某铁路为例探讨铁路噪声监测结果及防治建议

Taking a railway as an example to discuss railway noise monitoring results and prevention suggestions

通过对一条既有铁路改扩建工程的铁路外侧轨中心线30m处及距铁路外轨中心线65m以内敏感点的噪声监测与分析,结果表明,距离的远近是影响噪声值大小的关键因素,但不是唯一因素。针对此,从噪声源、传播途径及接受者等方面提出了一些防治措施。

Through the monitoring and analysis of the noise data at a sensitive point of 30m from the center line of the railway outside the railway and the center line of the railway outside the railway within 65m,the results show that the distance is the key factor affecting the noise value,but it is not the only factor. In view of this,some prevention measures have been proposed from the aspects of noise sources,spreading way and recipients.
