Mechanically stabilized earth (MSE) walls are composed of compacted soil material, facing panels, and reinforcement layers made of geogrids, geotextiles, or steel strips. A single-tier wall is commonly used when the wall height is small. However, when the wall height is large, a multitiered wall can be adopted to enhance the stability of the wall system. The deformation behavior of reinforced soil walls is complex and is often studied through numerical simulations. However, most domestic studies have focused on single-tier walls, and limited attention has been paid to multi-tiered walls. Therefore, this paper presents a numerical study of the deformation behavior of a two-tiered MSE wall. The objective is to investigate the influence of the following parameters on the wall deformation: the setback distance of the lower tier relative to the upper tier, the height ratio between the upper and lower tier, and the length of the reinforcement layers within the compacted soil.
