A p-y model for predicting the lateral nonlinear interaction between pile and soil-rock mixture material based on discrete element modeling

To obtain deep insight into and understanding of the mechanical behavior and evolution of the lateral interaction between a single pile and soil-rock mixture material (S/RM), parametric two-dimensional discrete element analyses were performed to investigate the effects of different rock proportions. Adequate numerical simulations for the S/RM were first studied and verified by field direct shear tests. The results demonstrated that the binary...
