Somebody can tell me is it logical to have a consolidation settlement so much so that the settlement (based on conventioanal Terzaghi formulae ) is almost equal or even exceed the the height of embankment placed (loading). i.e. there will be no net height gain even say a fill of 1m (about 20 kPa) is palced while the computed settlement is also 1m by calculation ? This sounds very unrealistic isn't it ?
It is possible to achieve settlement greater than the amount of fill placed. I have worked on an embankment where such movement has occurred. In this particular case, the subsoils consisted of approximately 40 feet of very soft soils with void ratios approaching 4.0 and compression indices near 3.0. The thickness of this soft stratum permitted remarkable settlement
