ANALYSIS OF VIADUCT AND GROUND VIBRATION INDUCED BY TRAIN LOADS

摘要

This paper is divided inGround vibrations induced by a train caused vibration nuisance problems in the vicinity of railway. The analysis model is divided into two parts in this paper, one is the viaduct, the other is the picket and ground. The viaductis modeled as an elastic beam, which supported by pillar. It is assumed that beam and wheels are ideally smooth and no carriage or wheel-axle vibrations are excited. According to this assumption the time domain integral representation is derived. The response of the ground and picket is simulated by FEM.
