abstracts | An incremental model is proposed to describe pre-failure behaviour of granular soils in plane
strain conditions. The model has been derived from an approach applied in the analysis of
triaxial tests. We have applied the methods of tensor algebra to transfer our triaxial results
to a 2D case. The model describes the pre-failure deformations of fully drained sands and
phenomena associated with undrained response such as static liquefaction. This model has
a simple structure in the form of incremental equations. For some simple loading paths, these
equations can be integrated analytically. For more complex loading paths a simple numerical
algorithms will be sufficient. The model takes into account an initial anisotropy of soil which
is ignored in most models. It also takes into account the initial state of soil, defined as rather
contractive or dilative, in addition to classical geotechnical division into loose and dense sands.
The proposed constitutive equations allow the study of pre-failure instabilities of sand, and
some examples are presented. We have also derived analytically the equation for an instability
line. |
