Q3/ A laboratory test was performed on a 25.4 mm thick, doubly drained oedometer sample of clay. readings taken in the test, the time (tso) for 50% consolidation was 8.75 min. The laboratory sample was taken from a saturated layer of clay that was 18 m thick. The layer was subjected to a loading that was very similar to that imposed in the laboratory test.
