AbstractConsolidation tests have been carried out at various constant rates of loading in an effort to define the time- dependent aspects of the consolidation of Leda clay. The tests, lasting from two days to three months, provide graphic evidence of the range of time effects for this clay. It has been found that the major time effects are concentrated around the preconsolidation stress level and that subsequently they diminish to more normal proportions. The tests have been asssessed with regard to the probable structural behavior of the clay. The results further emphasize the error of normal consolidation analysis around the critical zone of major time effects. The tests also appear to indicate a minimum rate of laboratory loading below which the time factor is of far less importance. One further conclusion points to a practical necessity to allow for quite large settlements at loads around the preconsolidation value.
