| 基于空铁联运战略规划和高速铁路提速要求，亟需开展高速列车下穿地下车站的噪声测试和评估。该文研究高速列车在250 km/h单车越行、300 km/h双车交会越行和进站停车工况下，穿越国内某机场地下车站时产生的噪声对站台的影响。实验一共测得3种工况下的多组噪声数据，并分别进行1/3倍频程频谱分析和A计权声压级评估。根据《GB 14227-2006》噪声标准，研究发现列车在3种工况下站台端部的等效连续A声级均未超过限值80 dB(A)。其中，列车在越行和进出站时产生的噪声频率主要分布在2500 Hz以下，而在停靠时怠速产生的噪声主要分布在1250 Hz以下。该研究验证了该地下车站噪声设计达标，列车可以以时速300 km/h全速越站；该研究还有助于为国内其他机场后续建设下穿高速铁路的综合交通换乘中心提供噪声评估参考。 |

| Based on the integration of air-rail transport and the development demands of high-speed railway speed enhancement, it is urgent to test and evaluate the noise of high-speed train underpass the airport. This study investigates the effect of noise generated on the platform of the high-speed trains crossing an underground station under three conditions (250 km/h single-train passing through, 300 km/h double-trains meeting and single-train entering and stopping at the platform). Multiple groups of the noise data under three conditions were measured in the experiments, which was subjected to 1/3-octave spectral analysis and A-weighting calculation. According to the GB 14227-2006, the results show that the equivalent continuous A-weighted sound pressure levels of the platform are lower than 80 dB(A) under the three conditions. In particular, the frequency of the noise generated by the train in the process of crossing and entering and leaving the station is mainly distributed below 2500 Hz, while the noise generated by stopping is mainly distributed below 1250 Hz. This study proves that the noise design of the underground station is up to the standard, and the train can cross the station with full speed at 300 km/h. This study can provide a noise assessment reference for the construction of underground high-speed train stations at other airports. |
