Study on the dynamic response characteristics of the concrete track and roadbed during the speed up tests of Gyungbu high_speed rail
경부고속철도 콘크리트궤도에서의 속도대역별 궤도 및 노반 동적응답특성 연구
Abstract
The concrete track was applied for Gyungbu 2nd phase high_speed railroad line as a basic track structure. Two track structures, ballasted track and non_ballasted concrete track, have a different train load transfer mechanisms. However, it's rare to see about research results related with it. So, to understand dynamic response characteristics of the concrete track and roadbed, we measured accelerations of carbody and bogie, vertical and lateral load, stress and displacement of rail, and earth pressures of subgrade at
