Behavioral Characteristics of the Roadbed with speed up in HSR

초록

There is no design code at the operation speed of 400km/h in the around world, but the most of the countries were operating high speed railway line have tried to develop the highest speed railway. During the speed up test from 300km/h to 421km/h, we were measured the acceleration and displacement of vertical at transitional zone of bridge-earthwork in the Gaya bridge. All measured data were satisfied with assessment criteria of roadbed with maximum speed at 421km/h.
