Influences of Loading Mode and Construction Speed on Position of Phreatic Line of a Tailings Dam
The location of phreatic line of a tailings dam is of significant importance on the stability of the tailings dam. In this study, extensive numerical analysis in ABAQUS have been performed to study the influences of loading mode and construction speed on position of the phreatic line of tailings dam in the process of construction from the existing elevation of 59 m to the final elevation of 100 m. The results show that the location of the phreatic line changes very little at the lower part of the dam; by contrast, the location of phreatic line dramatically changes at the upper part of the dam. At a certain construction speed, loading mode has negligible influence on the position of the phreatic line during the duration of one rising round for the tailings dam. The construction speed has more significant influences on the position of phreatic line in the middle term in the service duration of the tailings dam than in the later period.
