Abstract
The stability of tailings dams has become a critical concern for mining industry due to the recent tailings dam failures. The authors have presented a good paper to investigate the failure of tailings dam due to static liquefaction using the commercial FE code Plaix2D. Three procedures that can trigger static liquefaction were investigated in the paper, including surface load, toe deformation, and rise in phreatic surface. However, this discussion presents several simple observations regarding the simulation of the static liquefaction and additional analysis on the Fundão tailings dam.
