Abstract:For the study of seepage-stress coupling effect on the stability of tailings dam, based on seepage mechanics, fluid-solid coupling theory and intensity reduction method, the stability of tailing which based on the fluid-solid coupling are analyzed through finite element numerical calculation software ABAQUS, ?the results show that the stability considering the seepage will reduce compared with the stability considering the stress, while the stability considering the fluid-solid coupling will increase compared with the stability considering the seepage.
