Abstract : A more quantitative understanding of the response of reinforced soil walls to explosions in the retained fill was developed via a single degree of freedom model developed by Drake, et al (1987). A series of full-scale tests were conducted to investigate the response of the walls to free field blast pressures, and detailed analysis of the test data suggested inertial stresses generated during the crater formation process, not blast pressures, were the governing loading condition. Using full and small scale test data, the validity of the model is demonstrated through a consistent relationship between system stiffness and displacement. The consistency of the stiffness/displacement relationship for full and scaled tests suggest the centrifuge provides reasonable models of full scale reinforced soil walls. Application of the test data to the model yields order of magnitude results in prediction of ultimate wall panel displacements. The approach and results of this study provides a significant departure from previous research by identifying the loading mechanisms that govern response, the influence of the engineering properties of the materials, and validation of a model that provides a quantitative description of the physical response of the reinforced soil wall.
