[Abstract]: Elasto-plastic analysis for classical lateral earth pressures is presented in this paper using the explicit finite difference method of FLAC. The developed numerical model consists of a rigid structure for the gravity wall, a zero thickness interface for modelling the sliding and separation between the wall and the backfill soil, and a Mohr-Coulomb soil model for the backfill. The rigid wall was pushed into the backfill soil to induce passive failure and the ultimate load required for the failure is calculated. Numerical results are compared with other available solutions and numerical difficulties experienced in the analyses are discussed.
