Stability of sandy slopes under seepage conditions

Original Article


Stability against shallow mass sliding in saturated sandy slopes under seepage depends on the flow direction and hydraulic gradient, particularly near the ground surface. Two modes of instability i.e., Coulomb sliding and liquefaction have been studied and the critical flow directions discussed. The utility of the numerical approach in solving complex flow problems with irregular boundaries and surface topography is demonstrated by means of two slope examples with different internal drainage conditions. The numerical results for the seepage gradients at different points are compared with those predicted by the simple expression derived in this study, and the corresponding effects on the stability are evaluated.
