Based on the stochastic finite element method (SFEM)
the probability analysis has been done on the seepage failure of embankments. The influences of the variation of the coefficient of permeability
the change of the flood level and the geometry of the embankment on the failure probability of seepage are studied. The failure probability increases with the increasing of the variation of the coefficient of permeability. When the coefficient of variation increases to a certain value
the failure probability would cease to increase and then descend slightly. The failure probability increases with the increasing of the flood level. It also increases with the increasing of the angle of the embankment slope. Particularly
when the slope ratio is greater than 1:2.5 the failure probability increases rapidly.
