<p>Stringing particles are granular materials formed by connecting discrete particles with rope, and there is a lack of load-bearing behaviors and mechanisms of such granular materials. In this paper, the load-bearing mechanism of the stringing particles system is investigated by using the Discrete Element Method (DEM), and a discrete elemental model of the stringing particles is developed in YADE; the direct shear test of the stringing particles shows that contact of rope effectively enhances the load-bearing capacity of the granular system. The direct shear experimental model was established through the simulation platform, and the simulation results of each group of specimens coincided with the experiments, and the established model of stringing particles was reliable in predicting the load-bearing capacity of the particle system, and at the same time, the analysis of the chain of contact forces within the particles, the anisotropy, the ratio of effective rope-particle contact forces and the average contact force of effective rope-particle contact forces showed that the contact state of the particles in the specimens was changed by rope-particle contact forces and the degree of change was related to the rope-particle contact force.</p> Graphical Abstract <p></p>
