VIBRATIONS AND NOISE FROM TRAINS IN TUNNELS

This paper discusses some work that has been conducted to obtain relevant criteria for assessing the vibration impact of new railways, together with some calculation methods for predicting noise and vibration levels. The Transport Research Laboratory (TRL) has made extensive measurements of train vibration, providing extensive data from which to develop empirical models to predict the levels of vibration from various types of trains. Train and track characteristics affect the level of vibration near the train, and ground materials configurations affect the vibration's propagation to distant structures. Some evaluation criteria are described, relating to: (1) subjectively perceived vibration; (2) damage to buildings; (3) reradiated noise; and (4) critical working areas. The evaluation of potential noise and vibration impacts of new railway lines involves the calculation of various factors, including: (1) the day-time 16hr and night-time 8hr RMQ velocities; (2) the reradiated noise level expected inside buildings; and (3) the resultant PPV at distances up to 800m from the tracks. The corresponding evaluations for trains in tunnels involve calculation of: (1) vibration damage to buildings; (2) directly perceived vibration; (3) reradiated noise; and (4) critical work areas.
