Abstract

In this work is considered the problem related with a stressed state of railway embankments taking into account of dynamic loadings from high-speed trains. In the offered technical method is giving wave nature transmissions of dynamic loading from the passenger trains and their interaction of soil layers with various parameters. The design procedure gives a clear physical and mathematical pattern, where all formulas are in detail shown and simple for understanding. Calculation is conducted numerically in two stages. Considering from classical principles of structural mechanics, the first calculation stage of the railway structures includes deformation of the railway sleepers taking into account of a deflection of the soil bases. Further, on the basis of the received data from the first stage is conducting interactions railway roadbed structures with the soil bases. The second stage of calculation includes quasi-static and dynamic parts, where is considering the stressed and deformed states of the railway embankment from stationary and non-stationary loadings of the passenger trains. The received results of calculations are demonstrated the essential effect of the vibrating loadings from passenger trains to stress-deformed state of railway structures.
