摘要
铁路噪声预测模式研究已成为国际学术界和各国政府关心的一大课题。由于以铁路噪声为主的环境问题日益严重,给沿线居民的生活和工作带来严重影响,在项目设计初期进行准确的噪声预测是十分必要的。以声学理论为基础,从铁路噪声预测模式发展现状、噪声源类别及空间位置、户外声衰减特性等三个方面对国内外铁路噪声预测模式进行比较分析。概括总结了各国预测模式在噪声预测计算中的优劣,并提出了一些建议,以期为我国预测模式的完善提供一些帮助和启示。
Research on railway noise prediction model has became a major issue concerned by both international academic communities and governments. Nowadays, the daily life and work of the residents along the railway line are seriously affected by railway noise pollution, which makes the accurate forecast in the early design phase of a railway engineering project very urgent. In this paper, a comparative analysis, based on acoustic theory of the railway noise prediction model both at home and abroad, is conducted in three aspects., the development status of railway noise, the noise source types and spatial location, the outdoor sound attenuation characteristics. Meanwhile, the advantages and shortages in the noise prediction and calculation of the forecasting models of different countries are summerized, some proposals are offered, which are expected to supply experiences and inspiration for the improvement of railway noise prediction model in China.
