Abstract: The trend of land transportation is turning into railway/track transportation. Track transportation has many advantages, but the noise and vibration induced by the wheel/rail contact and the electrical corrosion of the stray current are sensitive to the neighboring residents along the track route. The modern track transportation was tried to solve the above problems, this paper research the noise and vibration prevention of the tunnel nonballast track in Taiwan. The study includs rail fastener system, vibration prevention nonballast track of the traditional railway, high speed railway, mass rapid transit and future view rail system. It is special to study the modeling of the floating slab track at Taipei mass rapid transit. The ABAQUS is used to analyze the floating slab track model, and to compare the practice measurement so as to achieve the desired results. We hope that the paper can provide practical experience and the results of the study, for the prevention of environmental vibration contamination in the tunnel track at the urban transportation, to other railway systems or the academia in the environmental field and railway field in the world.

Key words: tunnel track, vibration prevention, floating slab track
