摘要
This work investigates the seismic behavior of a tailings dam that will be raised by the center line method in a region of high seismic activity in Peru. Numerical analysis was performed to verify the liquefaction potential of the tailings, considering the UBC-Sand and Byrne constitutive models for cyclic loading generated by an earthquake of magnitude M-w = 8.2. The results of the analyzes are presented in terms of the pore pressure parameter r(u) as well as maximum permanent displacements in the tailings deposit. Although the fine tailings exhibit dynamic li-quefaction potential, the stability of the rockfill dam does not seem to be in jeopardy.
