Learning outcomes

The aim of the subject is to provide students with a theoretical basis of phenomena associated with railway substructure including of ballast bed, track-bridge interaction. The methods of static and dynamic analyses are presented, both analytical mathematical models and numerical methods of solution, especially FEM.


Structural mechanics, nonlinear mechanics, dynamics of civil structures, numerical mathematics, physics.
Soil mechanics, stability analysis of slope, earth pressures, soil compaction, improvement of soil properties, stabilization.
Railway structures, switches, railway track geometry components and alignment, design of railway tracks and stations.

Planned educational activities and teaching methods

Teaching methods depend on the type of course unit as specified in the BUT Rules for Studies and Examinations.


The objective of the subject is to deepen knowledge in railway substructure theory with respect to theme of PhD thesis.
