Analysis and control measures of vibration and noise sources in urban rail transit under the perspective of standard governance

With the rapid and large-scale development of rail transit engineering in China, the vibration and noise problems caused by rail transit operations are increasingly receiving widespread attention from all sectors of society. This paper is based on literature research and comprehensively analyzes the vibration and noise sources of urban rail transit. It systematically analyzes the composition, characteristics, and causes of vibration and noise in rail transit, and provides systematic governance measures for vibration and noise reduction in rail transit from two aspects: noise sources and propagation paths. The research results of this article have significant reference value for the engineering practice of vibration and noise reduction in rail transit.
