SECONDARY CONSOLIDATION EFFECTS IN THE APPLICATION OF THE VELOCITY METHOD

Two delta river clays from Tasmania are studied to examine creep behaviour for extended load increments of up to 14 days. For load increments of 24 hours or less, a prolonged history of creep causes a significant departure from purely hydrodynamic behaviour. Curves of pore pressure dissipation rate (ppdr) and settlement into (SR) are found to have different gradients in primary and secondary regions, suggesting that a complex combination of hydrodynamic and viscores mechanisms operate to some extent through the whole range of deformation. The secondary stage of the SR plot had to linear sections, neither relating to the terzaghi theory. A horizontal step occurred in the ppdr curve for all load increments prior to the onset of the viscous secondary stage. (TRRL)
