城市轨道交通噪声监测与评估

Noise Monitoring and Evaluation of Urban Railway Transit

近年来,乘坐城市轨道交通已成为市民出行方式的重要选择,与此同时城市轨道交通运行所产生的噪声也给乘客带来严重困扰。本文针对目前城市轨道交通运行振动与噪声问题现状,列举美国、欧盟和中国关于轨道交通噪声控制相关标准,梳理近年来国内外与城市轨道交通噪声监测与评估相关的研究内容与成果,重点介绍噪声监测、评估的三种创新方法,即噪声地图、声场有限元、BIM技术,并提出未来噪声监测应积极引进革新技术、加快各环节信息化与互联网化,全面提升噪声监测及评估水平的建议。

In recent years, travel by urban rail transit has become an important choice for citizens, but at the same time, the noise generated by the operation of urban rail transit has also brought serious trouble to passengers. In view of the current situation of vibration and noise in urban rail transit operation, this paper first lists the relevant standards of the United States, the European Union and China on rail transit noise control. Then it sorts out the research contents and achievements related to urban rail transit noise monitoring and evaluation at home and abroad in recent years. At last, this paper focuses on three innovative methods, namely noise map, sound field finite element and BIM technology for noise monitoring and evaluation, and proposes suggestions that noise monitoring should actively introduce innovative technologies, accelerate the informatization and Internetization of all links, and comprehensively improve the level of noise monitoring and evaluation in the future.
