Abstract:At present, the main method of design in soil nailing depends on the calculation of tensile force in reinforcement material. On the other hand, it has been considered that the bending resistance of reinforcement materials restrains the deformation of soil and leads to massing of the reinforced area. In this paper, model tests using iron ore for backfill material were conducted to investigate the effect of reinforcing force on the reduction of horizontal earth pressure. Furthermore, the soil arching theory was applied to investigate the interaction between the reinforcements and the surrounding soil. Key Words:reinforcement, soil nailing, earth pressure, arch action
