ON THE LINEAR RELATIONS OF V-1N-P AND IN V-1N-P FOR ISOTROPIC CONSOLIDATION OF SOILS

The well-known linear relation between the specific volume and the log arithm of the pressure for the isotropic consolidation has been widely incorporated into elastoplastic constitutive equations of soils. It i s, however, indicated in this article that this relation has several p hysically unaccepted properties. Instead of this relation it is recomm ended to incorporate the linear relation between both logarithms of th e volume and the pressure into constitutive equations, which does not have any of the unrealistic properties.
