In order to evaluate the propagation mechanism of traffic-induced vibrations on the soil and the building adjacent to both a national road and an elevated highway, microtremor tests and traffic vibration tests are conducted in twice. Under the ordinary vibration conditions for this site, it is understood that the vibrations caused by automobiles on the national road and the elevated highway coexist together on the soil, and that the vibration characteristic of a soil differs from point to point because of the differences of a distance and a direction from each road(vibration source). While soil responses in the EW(transverse) direction are strongly influenced by the traffic on the elevated highway, ones in the UD(vertical) direction are influenced by the traffic not only on the elevated highway but also on the national road. It is also cleared that the running conditions of automobiles such as classifications of roads, running velocities and loading conditions have great effects on the dynamic responses of the soil and the building.
