Abstract

Recently the construction of stations under railway lines and railway sections passing through central area of cities are increasing, calling for an urgent establishment of countermeasures against railway vibration and its subsequent second-phase noise. Of technology developed up to now, the most efficient countermeasure is the floating slab track, a track system isolated from the sub-structure by springs. Unfortunately, however, the system design technology and technology for key components have not yet developed in Korea. As such, in this study, the analysis and design technology of floating slab track and its vibration isolator technology can be achieved. In preparation for future demands, it is expected to raise awareness for the need of technology self-support and to make a meaningful contribution to mitigating vibration and noise produced by the next-generation high-speed railway.
