Transcribed Image Text:A square footing (2x2) m at a depth 1m from the surface, carrying a load of 4000 kN and resting
on soil profile as shown.
Given: eo=1, oc =70 KN/m², Ce =0.4, C=0.03, Cv=0.03 cm²/sec, Calculate the expected
primary consolidation settlement.
If the primary consolidation is 20 cm
1. What is the time in (days) required for 5 cm consolidation settlement to occur?
2. After 25 days, what is the amount of consolidation settlement.
