Maximum Slab Length of Floating Slab Track
플로팅 슬래브 궤도의 최대길이

Abstract
Recently, many railway stations are built under the railway line in urban area. The passage of railway vehicles generates mechanical vibrations of a wide range of frequency. Thus, it is required to place structural vibration isolation systems to reduce vibration and noise originating from surrounding environments. This study is to investigate the maximum floating slab length based on track/floating slab interaction analyses. Actions to be taken into account include temperature, braking/acceleration, bending of the deck, and creep/shrinkage. The additional rail stress has been chosen for the criterion for the maximum slab length. In addition, further analyses are performed to include the stopper which restrict the in-plane movement of the floating slab track. Several alternatives for stopper positions were thoroughly studied in this study.
