• In this study, the authors work out theoretical analysis of mechanical behavior of an RC earth retaining structure by. the Sakauchi method. In this case, the deflection and the bending moment of the structure, especially at the final stage of excavation, are supposed to be very large, as the final excavation depth is so deep as 27.5m. Therefore, we reinforce the lowest strut (slab) with an RC beam of non-uniform section or with a diagonal steel beam (composite beam), so that they may suppress these quantities at the final excavation. From these results, we conclude that an RC or a composite beam will restrain remarkably the wall rotation, thereby, decreasing the deformation of the wall.
