Reinforced earth retaining walls are easier to construct and more economical than concrete retaining walls, and the applicability to the parts where the retaining wall structures are needed is gradually increasing. Since 1980, reinforced earth retaining walls have been used in various ground and environmental conditions, and various types of damage have been found in the maintenance stage due to various conditions of the applied site. Especially, when the ground is sloped, the damage is more serious than the case where it is not. Therefore, in this study, the long-term behavior of reinforced earth retaining wall constructed on the expressway according to the slope of the ground is analyzed.
