Abstract

Based on the supposition for displacement mode of soil in passive region, using the Duncan-Chang model, a passive soil pressure computing formula considering nonlinearity of retaining wall displacement was proposed. Calculated results got by back analysis of model test were compared with measured results. Results show that the calculated results agree well with measured results. The formula in the paper which has advantages of simplification, good intelli-gibility, a few parameters and specific physical significance can reflect the nonlinear influence of displacement on passive soil pressure.

Key words
