A comprehensive approach to the dynamic response analysis of reinforced soil structures subjected to blast loading is presented. Themethod is based on an estimate of the pressure-time response at theboundaries of target structures using a two-dimensional versatile gas dynamic code (SPLIT2D). The soil-reinforcement response is simulated using a direct nonlinear approach that is implemented in the finite element computer program RESBLAST. Examples of this approach to investigate the response of a reinforced soil wall and a soil slope with and without reinforcement are presented. The results of rapid cyclic tensile loading tests are used to obtain mechanical propertiesused in the nonlinear reinforcement model implemented in the finiteelement code.
