STRESS-DILATANCY RELATIONS OF ANISOTROPIC SANDS IN THREE DIMENSIONAL STRESS CONDITION

The stress-dilatancy equations which relate principal strain increment ratio with principal stress ratio in the previous studies are first reviewed and shown is the necessity to investigate the relationship between the stress-dilatancy equation for axisymmetric deformation and that for general stress condition and to clarify the effect of inherent anisotropy on the stress"dilatancy equations. Then, in summary form, three fundamental postulates are introduced as the bases on which a theory to investigate above mentioned two problems is to be established. The stress-dilatancy performance of sands predicted by the proposed theory were compared with several experimental data obtained by other investigators. These data include those of triaxial compression and extension tests, general stress condition tests and plane strain tests. This comparison disclosed the relevance of the theory in spite of its simplicity.(a) /TRRL/
