In order to study the influence of the physical and mechanical properties of tailings materials on the stability of tailings dam,a lead-zinc mine in Hunan Province was used as the research object.After the sample was subjected to multiple moisture absorption-desorption paths through the unsaturated indoor triaxial shear test.The physico-mechanical properties of the drying-wetting cycles affect the strength characteristics of the tailings material.The experimental results show that the peak value of the deviatoric stress decreases with the increase of the number of drying-wetting cycles,and ten...
