It was at Prague's Institute of Theoretical and Applied Mechanics of the Czech Academy of Sciences in 1998 that basic research of earth/lateral pressure based on physical experiments and lately together with Czech Technical University in Prague also on numerical modelling was initiated and is still in progress there. The first research target is to prove a real soil mass behaviour and to do the theory more exact. The second one is to apply experimental results for numerical modelling and for development of an advanced software package SIFEL solving complex non-linear numerical models. The paper concentrates on double physical experiments (E5/0,1 and E6/0,1) with pressure at rest and passive pressure during wall rotation about the toe and their numerical modelling. The measurements from the both experiments exhibited almost the same results and therefore only the E6 experiment was selected for the numerical simulation. The nonlinear numerical simulation was performed with help of plasticity model based on Mohr-Coulomb yield criterion. An evaluation of physical experiments and numerical modelling is presented.
