Ground vibration measures and road evaluation for the RC hollow slab bridge

Abstract

The countermeasures work by reinforcing method with overlaid concrete was executed in the object bridge where the ground vibration problem was occurred. By these measures construction, it was confirmed that the ground vibration near the bridge decreased 3-5dB. According to the results of the dynamic response analysis under the running vehicle and the examination, the ground vibrations near the bridge were influenced by the road roughness at the object abutment. Therefore this study investigated the relation between the IRI_10 using the road roughness at the abutment and the vibration level of the ground vibration near the bridge.
