Abstract

The creep behaviour of Eemian gyttja was investigated by means of a triaxial creep test and a torsional shear hollow cylinder creep test. A low calcareous, mineral-organic gyttja with 12.0% of organic content IOM and 31.0% of calcium carbonate CaCO3 content, as well as a high calcareous, mineral-organic gyttja with 18.5% of organic content IOM and 66.5% of CaCO3 content were tested. Laboratory tests have shown an essential influence of time, and volumetric and deviatoric stress components on the performance of strain rate in the creep process. The empirical equation describing the relationship between the strain rate and time at shear stress levels smaller than the shear strength was verified at complex stress conditions created in the TSHC creep test. The average values of empirical parameters were evaluated from the analysis of calculation results.
