The rapid development of transportation and increases in vehicle speeds and vehicle weights have resulted in higher vibration and noise levels. In the meantime vibrations and noises that seem to have been tolerated in the past, are now more often considered to be a nuisance. Methodology of assessing ground-borne vibrations for railway traffic is presented based on the Federal Railway Administration （FRA） Guidance Manual-High-Speed Ground Transportation Noise and Vibration Impact Assessment. Effectiveness of wave barriers such as open trench, in-filled trench, and piers for reduction of vibrations induced by railways and the procedure for barrier selection are discussed. Finally, an example of vibration assessing of Suvarnabhumi Airport Rail Link is presented to demonstrate the methodology.展开更多
