It is often easy to cause overall or local damage of railway embankment in mountainous areas due to the complex topographic and geological conditions when constructing high-speed railway. With the development of geotechnically reinforced technology, more and more mountain railway embankments adopt geosynthetics reinforcement to solve the deformation damage of embankments, however, the dynamic response characteristics and deformation law of geotechnical reinforcement under inclined stratum conditions are still ambiguity. Therefore, based on the model comparison test between railway embankment with inclined bedrock reinforcement and without inclined bedrock reinforcement, this paper carries out the research on the dynamic response characteristics of geotechnically reinforced railway embankment under inclined stratum conditions. And a comparative analysis on the changing rules of the vertical displacement, acceleration, dynamic soil pressure, and geogrid strains of geotechnically reinforced railway embankment was conducted. It aimed to investigate the dynamic response characteristics of geotechnically reinforced railway embankment under inclined stratum. The results showed that the vertical peak displacement of the inclined bedrock embankment is slightly larger than that of the uninclined bedrock embankment, and the vertical peak displacements of both cases decrease with the increase of loading frequency. The vertical peak acceleration and vertical peak dynamic soil pressure of the inclined bedrock embankment are obviously larger than those of the uninclined bedrock embankment, and both of them increase with the increase of loading frequency and decrease with the increase of burial depth. When the depth of burial is the same, the soil below the loading center of the embankment has the largest peak vertical acceleration and peak dynamic soil pressure, followed by the side away from the bedrock, and the side near the bedrock has the smallest. The peak micro-strain of the grids of the embankment all decreased with increasing depth of embedment of the grids, and the two layers of grids near the top of the embankment decayed less, whereas the peak micro-strain of the grids of the inclined bedrock-reinforced embankment was about twice as much as that of the uninclined bedrock-reinforced embankment at the same loading frequency.
