Noise and Vibration Measurement and Analysis at a Metro Depot and Above Transit-Oriented-Development

To meet a fast-growing demand of the Transit Oriented Development (TOD) in China, this study aims at a better understanding of noise and vibration characteristics due to activities at a train depot of the metro system, as well as the transmission from the depot to above TOD. Noise and vibration field measurements at the Luogang depot are presented. Noise and vibration source at the depot, transmitting through structural elements to the depot roof plate, and finally to housing properties above the depot were evaluated. Wheel-rail induced noise and vibration from the throat zone featuring rail switches, from the test track at higher train speeds, and as trains entering the inspection and maintenance yard were investigated. The influence of using different track-forms for vibration mitigation was examined.
