Ground-Borne Vibration from Manchester Metrolink

摘要

The Trafford Park Line extension to the Manchester Metrolink light rail system included a planning condition to control the ground-borne noise from operating trams within a building in ITV's studios on Trafford Wharf Road. To determine the expected levels of vibration and noise within the studios, a series of vibration measurements and predictions were carried out during the detailed design stage of the project. These included source vibration measurements on the existing Metrolink network and ground vibration propagation measurements on site. A trailer-mounted sinusoidal vibration source was used in order to quantify the complete propagation from the source to studio, together with the resulting re-radiated noise. This paper describes these measurements and the subsequent analyses and assessment carried out to determine the anticipated ground-borne noise levels within the studio.
