摘要
随着我国高速铁路的飞速发展,高铁噪声污染已成为突出的环境问题。鉴于目前
我国高铁噪声仍沿用普通铁路噪声的评价方法,导致评价结果不能反映受影响人群
噪声烦恼程度,为此,研究新的高铁噪声评价方法是非常迫切的。
本文在大量查阅对比研究国内外关于高铁噪声评价方法及标准的基础上,以武
广高铁南部新城组团段作为案例,进行声环境现状监测,用噪声软件 Cadna/A 模拟
预测案例区沿线两侧等效声级 LAeq 与最大声级 LAmax,借鉴日本新干线噪声评价量
LAmax 及相应标准,进行噪声影响评价,并同步选择受噪声影响最大的村民,就高铁
噪声引起的主观烦恼情况进行人群调查,分别将人群烦恼程度与等效声级 LAeq、最
大声级 LAmax 进行对比,结果表明,最大声级 LAmax 比等效声级 LAeq 更适合评价高铁
噪声。
在此基础上,提出新的评价量——噪声变化率,进一步在整个案例区选择距高
铁不同距离敏感点的居民,进行烦恼反应的人群调查,计算相应的噪声变化率。为
分析烦恼程度与噪声变化率二者的相关性,本文提出以噪声烦恼指数来表达烦恼程
度,并分析噪声烦恼指数与噪声变化率的相关性,结果表明,噪声变化率与噪声烦
恼指数具有很好的相关性,其相关系数达 ,以此证明了以噪声变化率作为评价
量是能较好反映人的感觉影响程度的因而具有一定的合理性。进一步分析高烦恼所
占的百分比与噪声变化率的相关性,得到二者拟合方程的相关系数达 ,进而采
用计算不同噪声变化率对应的高烦恼百分比,进行噪声变化率的分级。
新评价量及其分级标准的提出,为我国高铁噪声评价方法及标准的改进提供了
借鉴。

Abstract
With the high-speed rail has been rapidly developed in our country, and the noise
pollution of high-speed rail has e a prominent environmental issue. As the noise
assessment is still using the traditional railway noise methods, which results in the
inconsistency between the evaluation results munity response. Therefor, the study
of new assessment method of high-speed rail noise is very urgent.
Based on parison of a large number of domestic and foreign evaluation
methods and standards of high-speed rail noise, we stimulated the LAeq and LAmax along
both sides of the Case Study Area, Wuhan-Guangzhou high-speed railway in the southern
section of town, via the noise prediction software Cadna/A, drawing on the Japanese
Shinkansen noise evaluation criteria. Moreover, the status of the acoustic environmental
impact was monitored by setting monitoring sections in the case area, and LAeq and LAmax
were analyzed based on the corresponding evaluation methods. Subjective annoyance
caused by noise was surveyed in the residential areas which were nearest to high-speed
