In the previous paper, we discussed the lateral thrust of backfill of two cohesionless soils facing at a nearly vertical plane. The present report deals with the backfill of two-layer system. Coefficients of lateral thrust are calculated by the proposed equation for various cases and the results are compared with experimental values for sand and gravel which are measured in a soil box of 1×1×0.6m. The experiments are also made on the case of the vertical boundary to examine the equation which appeared in the previous paper. The results prove that the proposed equations are reasonable in both cases of vertical and horizontal boundaries.
