A numerical solution method for the evaluation of the static and dynamic horizontal active thrusts exerted by a backfill, consisting of two or three layers of different properties, on a retaining wall is proposed in the present study based on the Mononobe-Okabe analysis. Using the proposed method, the efficient type in forming a backfill with two layers of different properties is analyzed. In addition, for the design examples of a backfill made up of two or three layers of different properties, the static and dynamic horizontal active thrusts computed using the soil property of each layer are compared with those obtained from the proposed method, and also the problems expected in design are presented based on the comparisons.
