PRIMARY AND SECONDARY CONSOLIDATION OF CLAY AND PEAT

THE DOMINANT VISCOUS MECHANISM GOVERNING THE CONSOLIDATION OF THE MAJORITY OF CLAYS AND COLLOIDAL PEATS IS DESCRIBED IN TERMS OF STRUCTURAL VISCOSITY AND THIXOTROPY. A SIMPLE RHEOLOGICAL MODEL OF AN ELEMENT OF SATURATED CLAY IS DEVELOPED AND SOLVED FOR ONE-DIMENSIONAL CONSOLIDATION. THE RESULTS GIVE ENCOURAGING AGREEMENT WITH A WIDE RANGE OF PUBLISHED BEHAVIOR OF CLAY AND PEAT. THE RHEOLOGICAL MODEL OF CLAY SKELETON CAN BE APPLIED DIRECTLY WITHOUT INTEGRATION IN THE CASE OF PARTLY-SATURATED CLAY WITH CONTINUOUS AIR VOIDS AND PROVIDES A SIMPLE THEORETICAL BASIS FOR PREDICTING THE COMPRESSION-TIME BEHAVIOUR. A CONSOLIDATION MECHANISM RELEVANT TO FIBROUS PEAT INVOLVES THE DRAINAGE OF A SYSTEM OF MICRO-PORES INTO A SYSTEM OF COARSER CHANNELS. THE BASIC PHYSICS OF THIS PROCESS HAS NOT YET BEEN ESTABLISHED AND NO SOLUTION IS OFFERED IN THIS CASE. RRL/A/
