- Abstract
Recently, the tailings dam accidents have frequently occurred caused by flood overtopping, which have great harmful to the downstream people`s lives, property safety and the surrounding environment. Based on similarity theory and take the tailings in Sichuan as test materials to doing the physical model test which was the reinforced tailings dam under flood situation during tailings dam failure process. The results indicate that: (1) The erosion gully of reinforced tailings dam has been significantly step appearance failure; the whole overtopping processes of the reinforced tailings dam can be concluded to five stages: the erosion gully formation stage the improvement of erosion gully, which got deepen stage erosion gully internal extended stage step appearance erosion gully formed stage step shape erosion gully in stable stage, the whole overtopping is significantly in step failure model; (2) the existence of the reinforced belts has obvious blocking effect on the developing speed of tailings dam destruction and the of depth width of erosion gully, the vertical and horizontal displacement, also as the change of internal stress of reinforced tailings dam are significantly less than the unreinforced. The results have been deeply analyzed the evolution law and failure mode of tailings stacking dam, and reveal the blocking effect of reinforced belts during overtopping destruction, having some new exploration on prevention and control of flood disaster.
