Estimate the settlement due to effects of primary compression plus secondary compression in a clay stratum 3 m thick where the compression index C_c
is 0.33 and the value for e₀
is 1.25. Settlement due to primary compression (or consolidation) is computed to be 45 mm and will require approximately 6 years to complete. Calculate the settlement expected after a 15-year time period by summing the primary compression and secondary compression (select a ratio for C_α/C_c
from the lower values of the typical range).
