...Xiang-Nan Wang; Yi-Zhao Gao; Xiang-Tao Zhang; Yu-Zhen Yu; He Lv Purpose The stress–strain behaviors of rockfill materials in dams are significantly affected by the anisotropy and grain crushing. However, these factors are rarely considered in numerical simulations of high rockfill dams. This study...
