Abstract
Population concentration and the resulting traffic jams are a common
phenomenon in modern society. Such problems are getting worse as time goes
on. Although the highway area increases every year, traffic jams still can’t be
solved effectively. So the popularity of land transportation is decreasing in
favour of track transportation. Track transportation has many advantages, but the
noise and vibration induced from the wheel/rail contact are sensitive to the
neighboring residents along the track route.
There are many complaints about noise and vibration from the residents along
the Taipei MRT (TRTS) line where the TRTS tunnel is underneath the building,
so TRTS decided to use one of best solutions to vibration prevention available to
the track engineer – Floating Slab Track (FST).
In this paper, the overall issues of the FST based on consideration of the local
area in the design stage were studied, including the mode of structure analysis,
the vibration isolating component, material, localized geotechnical parameters,
rail fastener, elastic coefficient, etc. We hope this paper can share our practical
experience and the results of the study for the vibration prevention in track at the
urban transportation for environmental pollution prevention, to other railway
systems or to academia in the environment field and railway field.
