The Integrative Pogram for Vibration and Noise Control in a Subway Depot with Superstructures

This paper is based on a summary of the characteristics of vibration and noise effect in metro depots and the status of vibration and noise control in subway superstructures, systematically analyzing the process and method of integrative control, including analysis of engineering condition, characteristics, and requirements; the selection and confirmation of the vibration and noise control standard; analysis and prediction of vibration and noise effect; formulation and implementation of an integrative plan for vibration and noise reduction; and measurement and evaluation of vibration and noise control methods. Finally, three aspects that need to be emphasized for the next phase were put forward, namely, the source of noise and vibration from different functional areas in the depot, the index of the vibration and noise control, and the effect of different vibration and noise reduction measures.
