Abstract
In order to examine the long distance propagation mechanism of environmental ground vibration which is made in a viaduct section, a field measurements was performed for this viaduct in which the vibration problem actually generated. The experiment with a model using the similarity rule in a gravitational field and two-dimensional FEM analysis were enforced to examine this mechanism. From these considerations, On the supporting layer and the surface layer, some part of the low frequency vibration was propagated to the long distance without the damping property by a distance from the vibration source.
