5- Find preconsolidation pressure for each curve (page 25). 6- Find compression index, Cc and swell index, Cs for each curve. Assume initial void ratio for all tests is 0.8. 7- Compare 5 and 6 and pick the appropriate equation for consolidation settlement (normally consolidated, overconsolidated or combined). 8- You do not need to calculate elastic and secondary consolidation. 9. Report the total settlement in each boring. 10- Calculate if 50% consolidation can be achieved within 6 months if the total surcharge applied is 2,400 psf. (C =0.00002 ft/min)
