Abstract

This paper studies particle crushing and the related anisotropy of the micro-behavior of calcareous sand during shearing by numerical simulation based on the discrete element method. By analyzing the macroscopic and microscopic responses of calcareous sand under different particle crushing rates, such as the direction of particle crushing and the strong contact force chain, the results show that with the increase of the particle crushing rate, the peak and residual deviatoric stress and the dilatancy decrease, while the concentration degree of particle crushing direction and strong contact force chain reduces, and the degree of anisotropy weakens.
