Experimental study on localized deformation behavior of reinforced foundation ground

In this paper, the behavior of real localized deformation of reinforced foundation ground was investigated based on the model loading test using the simulation of the ground by aluminum rods. A series of model loading tests with and without reinforcing materials was conducted. And not only the improved bearing capacity but also its localized deformation property were investigated using the picture processing analysis of the deformations on the photograph for every settlement steps. The results drawn from these investigations were 1) the mechanism of progressive failure for the reinforced foundation ground was clearly investigated as a result of localized deformation and this was totally different from that for unreinforced ground, and 2) the failure mechanism for different reinforcement condition such as the length and the stiffness of the reinforcement was compared in each other and these bearing capacities were also evaluated quantitatively.
