Abstract : The vibration-attenuation was quantitatively compared by 3-Dimensional finite element analysis using ABAQUS, with
respect to the change of the type of trackbed systems. Most common trackbed materials, including ballast and concrete
were applied to the track structure, and the train-speed was set as 300km/h as Korea Train eXpress (KTX). The result of
current study revealed that the ballast showed the most effective material for the vibration attenuation.
