PHYSICAL AND NUMERICAL EXPERIMENTS WITH GRANULAR WEDGES
This paper describes the development of a numerical model for discontinua, the discrete stiffness model. Comparison with physical observations on granular wedges indicates that the simple form in which the model reduces to a lattice analogue with nodes connected by discrete elements is adequate for granular media. The resulting solutions are shown to approach closely the previously derived elastic solutions. Examinations of the associated displacement patterns emphasizes the need for careful interpretation of displacement monitoring of earth and rock structures for stability purposes. (Author/TRRL)
