Abstract Concerning dynamic assessments of railway bridges with ballasted track, the input parameters applied in calculation model significantly influence generated results. In this context, there is still a considerable need for research, especially regarding properties ballast superstructure. This contribution dedicated to an experimental investigation longitudinal track‐bridge interaction (T...

in this paper, the main factors in the analysis of the railway concrete sleepers areinvestigated and new recommendations are made in order to improve the accuracy of the currentpractices in analysis of the railway track system. first, a comprehensive literature survey isconducted, then, fem models for a railway track system are developed and used to discuss andevaluate the assumptions commonly ...

The calculated dynamic behaviour of railway bridges during high-speed traffic differs from the actual its bearing structure. In case steel bridges, calculations often overestimate vibration responses and therefore lead to uneconomical results. This gap between calculation measurement constitutes a complex research issue, whereas consideration ballasted track in has major influence. Concerning d...

Debris flow occurring in mountainous areas can cause issues to railway tracks. may large track deformation and even breakage introduce server ballast fouling afterwards. After the flash of a debris flow, fine particles be retained layer significantly reduce drainage, leading lower bearing capacity higher risk lateral stability problems. Moreover, these solid deposit on surface endanger train di...
