我国目前城市轨道交通高架线噪声的控制标准尚属空白，噪声控制指标和限值均参照《声环境质量标准》(GB3096—2008)。详细分析现行《声环境质量标准》的昼间等效声级、夜间等效声级噪声控制指标及限值在城市轨道交通高架线噪声控制方面的不足，在对比分析国内外其他噪声标准的基础上，针对国内城市轨道交通高架线噪声影响的特点，提出列车通过时段等效A声级噪声控制指标及限值的补充建议，增加早晚时段以及背景噪声增量的影响，可作为城市轨道交通高架线噪声控制的参考。

At present, a noise control standard for viaducts in China is still lacking, and control indexes and limits are based on the “Environmental quality standard for noise” (GB3096—2008). Therefore, in this study, the deficiencies in the noise control indexes and limits of daytime and nighttime equivalent sound levels in the current “Environmental quality standard for noise” (GB3096) are comprehensively analyzed. Based on a comparative analysis of other noise standards at home and abroad, suggestions on the equivalent A-level noise control index and limit value of the train passing period are provided according to the noise impact characteristics of domestic viaducts, which increases the impact of morning and evening periods and background noise increment, which can be used as a reference for noise control of viaducts.
