Construction Experiment of Reinforced Soil Wall Using Reinforcement Member Incorporating Both Friction Resistance and Bearing Resistance

A newly developed reinforced member incorporating both a bearing resistance and a friction resistance was confirmed the effectiveness using a prototype reinforced earth wall. The axial forces of the reinforcement members installed in the prototype reinforced earth wall were measured through a construction experiment and a field measurement. As a result, the measured axis forces of the reinforcement members increased during the construction of the reinforced earth wall. Then, the most of the axis forces of the reinforcement members were kept constant after the construction. The resistances by both the friction plate and the bearing plate occurred from the early stage of the construction, and then converged at the final stage of the construction. The measured friction resistance was greater than that of the bearing resistance at the upper part of the reinforced earth wall. On the other hand, the contribution ratio of the friction resistance decreased with increasing the overburden pressure, and converged to about 40 %.
