Numerical Study of Soil Anisotropy
Publication: Journal of Engineering Mechanics
Volume 118, Issue 1
Abstract
The effect of using an isotropic soil plasticity model to analyze the behavior of a sheet-pile wall supporting an anisotropic cohesive soil is investigated numerically using the finite element method. The stress-strain behavior of the soil is represented by an anisotropic and an isotropic constitutive models and the predicted behavior in each of these cases is compared. The results are found to depend significantly on the value of the coefficient of earth pressure at rest, . The study indicates that when theoretically consistent values are used for , the error in the predicted displacements as a result of neglecting the anisotropy is in the order of 40%. When a more realistic (lower) value is used for , the error decreases to about 25%.
