Abstract: The purpose of this note is to demonstrate the dependence of the behavior of a rigid retaining wall on the construction sequence of the backfill. The accretion process was analyzed through an incremental finite element method with a nonlinear soil having the characteristics of Ottawa sand. Although a relatively simple analytical model was considered, other inclusions might have been: 1) the effects of flexibility of the wall; 2) more complicated interface conditions; 3) backfill compaction; and 4) various constitutive relationships for the soil, which may occur in future work.
