Le problème décrit par la présente invention est de fournir une structure de paroi de retenue à faible coût qui peut former une face inclinée ayant une face incurvée tridimensionnelle, la structure de paroi de retenue, qui peut empêcher un glissement de bloc de paroi de retenue en raison de la pression des terres à partir du côté face arrière, permettant la réduction des travaux de construction manuels dans la mesure du possible et la construction avec un seul dispositif mécanique tel qu'un véhicule de grue, et pouvant s'appliquer à une gamme de matériaux de remblai ayant une grande variété de propriétés. La solution selon l'invention concerne une structure de paroi de retenue qui est construite en combinant un bloc formant cylindre et une structure de renforcement comprenant un élément d'ancrage joint au bloc formant cylindre, un élément de résistance disposé à l'opposé de l'élément d'ancrage, et un élément de liaison reliant l'élément d'ancrage et l'élément de résistance.
