INTERPRETATION OF CREEP OF SOILS BY RATE PROCESS THEORY

Experimental data from 4 types of soils is used to analyse, in terms of effective stresses, distortional and volumetric creep on the basis of rate process theory. In the course of creep, either time- (and strain-) dependent structural hardening or softening occur, the first one being typical for volumetric creep, the second one for distortional creep. Some deviations are to be expected with anisotropic soil structure (for example, with presheared samples). Rate process theory, intended for the description of secondary creep rate, may be geheralized by taking into account the structural changes of soils (hardening and softening of structure, as characterized by the increase or decrease of the number of structural bonds). In such a case, secondary creep results from the balance of strain-hardening and strain-softening (the first one typical for primary creep, the second one for tertiary creep), which is delicate enough for secondary creep to extend through more than a small time interval.
