Abstract
This paper describes how population concentration and the resulting traffic jams are a common phenomenon in modern society. Such problems are getting worse as time goes on and although the highway area increases every year, traffic jams still can’t be solved effectively. So the popularity of land transportation is decreasing in favor 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.
