The study considers the case of a cohesionless elastic–perfectly plastic backfill with a Mohr–Coulomb yield criterion and an associative flow rule in drained conditions. A kinematically admissible soil–structure failure mechanism is proposed and compared with the conventional solutions and with results from a numerical finite element modelling. The study shows that the proposed solution and the numerical solution are in good agreement. These solutions are found to be much more favourable for the wall than the conventional solutions.soil mechanicsInteraction sol-structureappuicisaillementplastic analysisanalyse plastiquesoil-structure interactionsupportshearMécanique des solsAnalytical and numerical analyses of the load-bearing capacity of retaining walls laterally supported at both endstext::journal::journal article::research article
