With raining model and evaporation model,unsaturated-unsteady seepage analysis was used to calculate pore pressure of the case slope,and Bishop Equilibrium balance method with total cohesion was used to calculate the stability factor of the case slope.

In calculation of unsaturated unsteady seepage through embankments, the initial phreatic level affects the calculated result significantly.
