Discrete element analysis of cushion soil arching effect of rigid pile composite foundation in high-capacity yard

Description

This dataset contains the PFC2D discrete element model files, calibration data, and simulation results supporting the study by Yang, Li, and Zhang. The study investigates the formation, evolution, failure, and reconstruction of soil arching in the cushion layer of a rigid-pile composite foundation under surcharge loading, focusing on the effects of geogrid reinforcement, cushion particle friction coefficient, and cushion thickness.
