ABSTRACT: A novel remedial design solution was developed to construct a reinforced soil wing wall on soft soil treated with nonconforming short dynamic replacement columns. The solution comprised (i) a detached connection system to allow for greater tolerable movement of the wing wall, (ii) installation of stone columns underneath the reinforced soil block as well as the wall facing, and (iii) the use of a dead-man anchorage system to tie-back the ground beam that underpins the wall facing. This paper focuses on the numerical analysis of the remedial wing wall system, and compares its prediction with actual performance.

RÉSUMÉ: fondation ballastés. La solution consiste en (i) une connection flexible permettant une plus grande mobilité du mur incliné, (ii) llastées en dessous du bloc de terre armée de même que les parements du mur, et (iii) , et compare le comportement théorique du mur avec le comportement observé.
