京沪铁路提速后环境噪声影响分析

The Analysis of Beijing/Shanghai Railway Environmental Noise after Increasing Running Speed

通过理论分析、类比预测的方法，对京沪铁路提速后，可能产生的环境噪声影响进行分析。预测分析结果表明，京沪铁路沿线大部分区段的铁路噪声接近或略超过７０ｄＢ（Ａ），较提速前的铁路噪声影响均增大２～３ｄＢ（Ａ），沿线受铁路噪声影响的居民人数约增加１０％。

Based on theoretical analysis and prediction,analyses the affect of Beijing/Shanghai railway environmental noise after increasing running speed.The results show:The railway noise is around 70dB(A) at most areas;the noise level increases about 2～3 dB(A);the population affected by Railway noise increase around 10%.
