The soil-bag has the large bearing capacity to the external force, because the materials inside soil-bags are wrapped and confined completely by the bag. In this study, the compression tests and cyclic shear tests were performed to evaluate the mechanical characteristics of the soil-bags for the design of the reinforcement soil by bags. As the results, the experimental compression baring loads almost agree with the theoretical values and the characteristics of the high performance hysteresis damping of the piled up soil-bags were found out.
