Study on the quantification of void between floating sleepers and ballast bed in th high-speed railroad line

고속철도 뜬침목 발생량에 대한 정량적 연구

Floating sleepers in a ballasted track increase both track deterioration and track irregularities. Consequently, a considerable maintenance work is required and maintenance cycle is shortened due to the floating sleepers. This paper quantifies the degrees of void between the floating sleepers and a ballast bed. In the future, the influence of floating sleepers on the track will be investigated by an analytical method using a dynamic model.
