Comparisons between the results of backfill placement analyses using finite element and the conventional equilibrium analyses indicate that conventional analyses are conservative. The finite element analyses indicate that the backfill exerts downward shear loads on the backs of retaining walls. These shear forces have a stabilizing effect on the walls. Shear loading ranged in value from 0.09 to 0.21, depending on the geometrical features and the values of the material parameters involved in the problem. In general, as the wall moves away from the backfill, the lateral forces exerted on the wall by the backfill decrease, and the lateral forces exerted on the front on the wall by the toe-fill increase.
