One of the methods of stabilizing embankments is the implementation of anchored walls, which is one of the common methods of restraining types of walls is the use of anchor plates. Also, Back to Back Mechanically Stabilized earth walls is one of the types of so-called mechanically stabilized earth walls with complex geometry, whereas their use has been less the subject of research. So far, no special research has been done to investigate and analyze the behavior of anchored back-to-back sheet-pile walls with anchor plates under a load of shallow foundations and the behavior and interaction of two walls with each other and the interaction of sliding surfaces of two walls and sliding surfaces of shear failure of subsurface soil. Since the effect of the interaction of two back-to-back walls with each other and the loading plate(shallow foundation model) with two walls due to the interference of their failure surfaces, strongly affects the load-bearing capacity and stability of walls, so in this article by physical modeling, The effect of horizontal distance between two walls, dimensions of loading plate on stability, load-bearing capacity and soil failure model under foundations and walls have been investigated and analyzed. In order to survey the shape, form and how the critical failure curves of the embankment behind the walls intersect, the Particles Image Velocimetry technique has been used. The results show that the effective distance between the two back-to-back anchor plates walls is about 130-120 cm, equivalent to 20-30 cm distance of their anchor plate.
