CLOSURE OF GENERAL STRESS-STRAIN-TIME FUNCTION FOR SOILS

THE WRITERS THANK BARDEN AND POSKITT FOR THEIR DISCUSSION AND AGREE THAT THE EFFECTIVE STRESS RATIO MAY BE A USEFUL PARAMETER IN PLACE OF THE DEVIATOR STRESS. THE MOST SUITABLE IN ANY CASE WOULD DEPEND ON THE PURPOSE TO WHICH THE RELATIONSHIP IS TO BE PUT AND THE ACCESSIBILITY OF THE QUANTITIES TO MEASUREMENT OR PREDICTION. THE WRITERS ARE ALSO INVESTIGATING A RHEOGOGICAL MODEL TO REPRESENT GIVEN EQUATION NUMBER 9. THE GENERALIZED FUNCTION IS NOT INTENDED TO SUPERSEDE PRIMARY CONSOLIDATION THEORY BUT MAY SERVE AS A MEANS FOR SUPERIMPOSING SHEAR DEFORMATIONS AND VOLUMETRIC DEFORMATIONS. THE GENERALIZED FUNCTION, HOWEVER, HAS BEEN STUDIED IN DETAIL ONLY DURING UNDRAINED DEFORMATIONS AND UNDER CONDITIONS OF APPROXIMATELY CONSTANT PORE-WATER PRESSURE. STRESS-STRAIN RELATIONSHIPS ARE DISCUSSED IN RELATIONSHIP TO SECONDARY DEFORMATION. THE FUNCTION PRESENTED BY THE WRITERS HAS BEEN FOUND APPLICABLE TO DRAINED CONDITIONS AS WELL AS UNDRAINED CONDITIONS, HOWEVER, CERTAIN PARAMETERS CANNOT BE ANTICIPATED TO REMAIN THE SAME UNDER BOTH CONDITIONS. DRAINED AND UNDRAINED CREEP BEHAVIOR MAY BE RELATED IN A SYSTEMATIC MANNER. THIS POSSIBILITY IS UNDER STUDY. REFERENCES: GENERAL STRESS-STRAIN-TIME FUNCTION FOR SOILS, AWTAR SINGH, JAMES K.
