Finite deformation models and field performance

This paper reports about the derivation of a fully nonlinear model characte rized by finite deformations without smallness assumptions. The soil is ass umed to be saturated, and no restrictions are introduced on the constitutiv e laws. Initial boundary value problems are formulated with reference to ge otechnical problems, such as consolidation under own weight or sedimentatio n of solid particles in a quiescent fluid, and back-analyses of field perfo rmance of an embankment resting on a soft clay deposit.
