Abstract

In this paper, a theory regarding the zeroextension line method for axial symmetry has been developed. The method assumes that the soil will yield progressively in accordance with the Mohr-Coulomb failure criterion. A simple approach has been employed for the derivation of equations, which is completely different from the method of characteristics. Equations satisfying equilibrium and yield have been directly written along the zero extension lines to allow the calculation of stresses and displacements at the same points in the soil mass. The governing equations have been shown to be more general in the axi-symmetriccase so that those for plane strain cases can be deduced from them. The mobilized strength in soil is related to shear strain. The finite difference form of the equations has also been put forward and the steps towards calculation of the fields have been presented. The most important application of the theory is the prediction of the load-deflection curves for structures in contact with soil. This has been shown using examples of circular footings on clay and sand. It has been concluded that the :zero extension line theory provides a relatively simple analytical method for the prediction of the load-deflection curves in both axi-symmetric and plane strain problems in soil mechanics.
