Analysis of the Behavior of Section thickness Slab Track Considering the Increase in Train Speed

HONAM High Speed Railway project is under construction with the target to have whole section in concrete track in order to decrease total life cycle cost (LCC) and the track destruction. The study, 'Development of high speed railway infrastructure system trial application for 400km/h' is on going in order to strengthen bed for the high speed railway. The flexural stress has been analyzed leading us to prove the vertical track settelement according to the variation of design load and train speed, by method of Eisenmann and Finite element analysis. And also, the concrete track's correlation between speed and the thickness of standard bed or slab behavior.
