The study of the influence to the traffic vibration on the ground and countermeasurement of improving roughness near the expansion joint.

Abstract

This paper presents the result of the study of the influence to the traffic vibration on the ground.Vibration on the ground, it is not clear how to exchange vibration characteristics with roughness near the expansion joint. Then we had vibration test and roughness measurement in girder of highway bridge, and we examined the relation between roughness and vibration.As the result, it is clear that vibration caused by roughness near the expansion joint effects ground vibration, and a factor in ground vibration.
