VISCOUS BEHAVIOUR OF SOIL UNDER OEDOMETRIC CONDITIONS

The viscoplastic constitutive theory of Perzyna, and Olszak and Perzyna has been modified and used to model one-dimensional compression of cohesive, normally consolidated soils. Predictions of the model have been compared with the results of a few nonstandard oedometric tests. The model simplifies the one-dimensional creep theory of Yin and Graham by eliminating the traditional concept of plastic strain. Both stress- and strain-controlled tests are discussed. The reference time 't0' used in the literature for the description of creep subsequent to a load step has been shown to be a function of the overconsolidation ratio. (A)
