Q. Computation of Settlement?
The settlement in any soil mass under an applied stress is given by
s = si + sc + ss
where,
S = total settlement,
Si = immediate (or elastic) settlement,
Sc = primary consolidation settlement, and
Ss = secondary consideration'settlement.
In granular soils, elastic settlement is the predominant part. In inorganic silts and clays, the primary consolidation settlement probably predominates. The secondary consolidation settlement forms the major part of the total settlement in highly organic soils and peats.
Creep occurs (secondary compression) after consolidation settlements. We defined consolidation settlement, as that compression during which excess pore pressure exists in the strat
