A Study of the Elastic Vertical Displacement of a Roadbed and HSB with an Increase in Speed on a High Speed Concrete Track (HEMU-430x)

In Korea, a speed up test of a train was performed on a high speed railway. The name of the vehicle is HEMU-430x. While the train increased speed from 300km/h to 421km/h on a railway track designed for 350km/h, elastic vertical displacement was measured on the transition zone of bridge-earth in the Gaya overpass bridge. Until the train speed reached 421km/h, the maximum of elastic vertical displacement measured 0.061mm on top of a reinforced roadbed and 0.311mm on top of a HSB (hydraulic stabilized base). Maximum vertical displacement of HSB measured at 383km/h, displacement decreased over 383km/h. Vertical displacement of reinforced roadbed increased according to the increase in train speed.
