To provide a vibration isolation structure of a viaduct capable of controlling oscillation frequency having about 20 Hz especially among vibrations generated in the case a car such as a train or the like goes through in the viaduct.
In the viaduct, a plate 5 is made of a carbon fiber composite material, it is located among cantilever beam 34, rail 8, sleeper 7 and ballast 6 and, at the same time, it is built on the cantilever beam 34 of the neighboring unit viaduct 3. The plate 5 prevents the cantilever beam 34 from being moved upward by jumping up in the case the train thereby goes through. In this case, vibrations of oscillation frequency of about 20 Hz having difficulty in making control can be controlled in the viaduct taking measures to cope with the vibrations by a conventional reinforced method.
