Ground vibration analysis methods for Light Rail Transit(LRT) on bridges are studied. LRT loads acting on the piers are evaluated considering interactions between trains and a bridge. Two dimensional in-plane and axisymmetric wave propagations are used in ground vibration analyses, and then the results of them are compared one another. A modified axisymmetric method is presented, which can consider the effect of the train loadings on a series of piers as the train moves. Parametric studies are carried out for various train speeds, bridge types and geotechnical conditions to investigate the characteristics of ground vibrations.
