On the Issue of Hydrodynamic Forces Acting on Coastal Railway Structures

Purpose: Numerical modelling of the storm wave impact on the coastal protection structures and railway tracks in the areas of intensive coastal storm tides has been performed. The intensity of the hydrodynamic impact on structural elements and the indirect effect of man-made structures on coastal erosion have been evaluated. Methods: Computer simulation by SPH method. Results: A map of the sea-wave velocity and overpressure distribution for incoming and reflected waves for a coastline zone has been built. The study has shown the benefits of inserting coastal rail facilities in the natural landscape. Practical significance: A comparative analysis of the stated-above hydrodynamic impact on the standard and alternative railtrack substructure in the coastal area has been conducted.
