Based on full-scale and model experiments using a seismic platform and vibration disturbances from rolling stock during high-speed movement, additional functions affecting the dynamic stability of the railway roadbed have been identified. The calculation formulas for ensuring the seismic resistance of railway culverts with the determination of the influence of the slope of the terrain of the road and the speed of trains have been clarified. If the core is reinforced with geotextile after 0.5 m, the soil layer above the pipe can be reduced to h = 1.5 m, which significantly reduces the excavation volume and the rail-sleeper grid's slopes. In addition, the magnitude of long irregularities that occur in the pipe area decreases, increasing the repair time of roads and the resistance to seismic forces. When conducting experimental studies on models, when focusing on this coefficient, there is no need to bring the model of the structure to destruction, which saves time and building materials.
