A GENERAL NONLINEAR MATHEMATICAL-MODEL FOR SOIL CONSOLIDATION PROBLEMS

This paper presents a three-dimensional consolidation model, based on mixture theory. Both the Eulerian and the Lagrangian formulations are given in one dimension for finite strain and general material nonlinea rity. Then the paper formulates the initial boundary value problems re lated to several situations of relevant geotechnical engineering inter est, such as consolidation between draining and impervious boundaries subjected to stress and/or velocity conditions, consolidation under ow n weight of a layer growing due to deposition of wet material, or to s edimentation of solid particles in a quiescent fluid.
