A Review of Studies on Ground Vibrations Induced by a Running Train
Osamu YOSHIOKA
Train-induced ground vibrations sometimes cause vibration nuisance problems along the right of way. It has been studied how to clarify basic characteristics of the vibrations and how to obtain practical methods for assessing and reducing them. This review presents the current status of studies about the vibration problem mainly taking the case of Shinkansen. It also summarizes some difficulties encountered in the studies. At present a few practical methods are available for predicting and reducing the vibrations. However, our practical knowledge is still poor because of considerable complexities of the generation and propagation mechanism. To solve the practical aspect of the problem, the basic aspect has to be further studied.
