Abstract

Aiming at the assessment of train induced vibrations in the neighborhood a preliminary theoretical investigation is conducted by assuming a Ricker wave torm loading with probable period on an embankment track. The track is assumed to be constructed on a soil stratum. The transient responses are computed by applying a hybrid method of finite elements (FE) and boundary elements (BE). The time domain Green function for a stratum is implemented into the latter formulation. The response reduction measure called WIB (wave impeding block) which is based on the cut-off frequency of wave field is investigated when installed in the embankment track. Parameter studies 'are performed for the rigidity ratio between emba
