“…The failure mechanism and bearing capacity of reinforced soil subjected to footing load were studied by Binguet and Lee [5], Schlosser and Elias [6], Huang and Tatsuoka [7], Huang and Menq [8], Yamamoto and Kusuda [9], and many others. For designing purpose, some investigators have performed numerical simulations using finite element (FEM) method [10][11][12][13] or finite difference program [14,15] to predict the ultimate bearing capacity of reinforced soil and to optimize the arrangement of reinforcement elements beneath the footing.…”
