taking primary vs secondary and primary consolidation when calculating settlement
taking primary vs secondary and primary consolidation when calculating settlement
(OP)
Hello
For civil pe preparation, On 6 minute solutions for geotech book, problem 42. why does it say it is normally consolidated and take only primary consolidation into account and not secondary consolidation as well?
it is basically a question that has sand and below the sand there is clay. you excavate some of the sand and refill and apply surcharge. it asks for the clay settlement underneath.
Thanks

"very few soils are "normally consolidated" since, if they are not recent (and still undergoing consolidation settlement by self weight), aging has an effect of providing a bit of preconsolidation to a clay so using normal consolidation only would be a bit to more conservative."
could you explain here a little more?
