铁路沿线新建住宅小区声环境预测与控制方法

Prediction and control method of sound environment for newly-built residential area along the railway line

文章针对铁路沿线住宅小区声环境质量差的状况,通过调研及现场实测,分析铁路噪声的特性、空间分布和传播规律,对拟建住宅小区的声环境进行评估、预测模拟,提出该地块建设中应采取的防治对策及措施,在建设过程中进行跟踪测量,进一步分析建成前后的声环境,寻求最佳的铁路噪声治理方案,以保证住宅小区获得良好的声环境质量,同时对各种措施进行经济技术等方面的比较。

Aiming at the bad sound environment in the residential area along the railway,through the site investigation and measurement,this paper analyzes the characteristics,spatial distribution and transmission rules of railway noise.Then the paper predicts and simulates the sound environment in planned residential area,and puts forward the noise control measures.The measurement of sound environment in the area is carried out during the whole construction process to further analyze the noise environment before and after the construction of barrier wall.Different countermeasures are also compared from such perspectives as economy and technology,etc.The study is undertaken to find out optimal countermeasures to railway noise so as to provide a great sound environment in residential area.
