Question
  1. A normally consolidated clay layer, 3 m thick, has the following properties :

Initial void ratio, e0= 0.8

Compression index, Cc = 0.25

Average effective pressure, σ’0 = 125 Kpa

Expected pressure increase, Δσ’ = 45 Kpa

Secondary compression index, Ca = 0.02

Time of completion of primary settlement = 1.5 years

What is the total settlement of the clay layer five years after the completion of the primary settlement?
