It is evident that the rainfall has a remarkable effect on slope stability. When the highly weathered soft rock is used for high-filled embankment slope
compacting factor directly effects on permeability and intensity of embankment soil . Transient seepage due to the rainstorm infiltration is computed using the finite element method. The computed transient pore water pressures are then used for limit equilibrium analyses of landslides. And effects of matrix suction on shear strength of unsaturated soils are considered. Effects of the compacting factor and intensity and duration of rainfall events are discussed. The results show that when rainfall intensity reaches 200 mm/d
the slope is instable. And the compacting factor of strong weathered soft rock used for high-filled embankment should not be less than 90 %; which is provided scientific basis for the treatment of high-filled embankment slopes.
