Abstract Based on the formation characteristics of tailings dams，the rigorous nonlinear analysis is made on the coupling of seepage and stress fields in tailings dams. Moreover，the governing differential equation is derived from the theory of elasticity and seepage on the coupling problem of stress and seepage fields. Then the corresponding finite element formulae and program are developing. Finally，the unsteady seepage analysis is made for the tailings dams. The result of an engineering example shows that the total seepage is less，but the maximum stress is bigger because of coupling considered.
