摘要
分析了新建铁路对城市噪声的影响特点 ,笔者认为除了铁路运输噪声外 ,由铁路引起的次生环境噪声影响也较大 ,包括站区噪声及车站引起的周边新增道路交通噪声。这些噪声特点各不相同 ,但都受铁路规模大小影响。噪声预测方法应在考虑铁路规模的同时 ,针对不同影响特征建立不同预测方法。
Characteristics of urban noise impact by newly built railway are ana lyzed. The result shows that the noise impact includes not only the noise from t he railway itself, but also from the secondary environment, that is the noise fr om train station and city traffic, which is somewhat different from the railway. However, the noise impact is interacted by the scale of the railway. Noise from different sources has different features. Different noise monitoring and predic tion methods should be used for the noise from different sources.
