The migration of fine particles under hydraulic scenarios is a primary cause of deterioration and even failure in many geotechnical structures. The particle migration test of the two-layer structure of the gravel and sandy-silty mixture under cyclic loading was performed to analyse the properties of particle migration under cyclic loading—hydraulic coupling. The results show that the variation in mud turbidity is influenced by both the fines content and the effective particle size. The particle size distribution of the sandy silt sample exhibits significant changes post-test. The upper layer of the sandy silt sample experiences the most substantial loss, while the middle layer shows a negative comprehensive loss, and the lower layer displays a positive loss. This research enhances our understanding of particle migration mechanisms in saturated soils subjected to cyclic loading, providing crucial insights for the stability assessment of railway substructures.
