An undisturbed soil sample was taken from the middle of a clay layer (i.e., 1.5 m below GL), as shown in figure. The water table was at the top of clay layer. Laboratory test results are as follows:
Natural water content of clay - 25%
Preconsolidation pressure of clay - 60 kPa
Compression index of clay - 0.50
Recompression index of clay - 0.05
Specific gravity of clay - 2.70
Bulk unit weight of sand - 17 kN/m3
A compacted fill of 2.5 m height with unit weight of 20 kN/m3 is placed at the ground level.
Assuming unit weight of water as 10 kN/m3, the ultimate consolidation settlement (expressed in mm) of the clay layer is
Natural water content of clay - 25%
Preconsolidation pressure of clay - 60 kPa
Compression index of clay - 0.50
Recompression index of clay - 0.05
Specific gravity of clay - 2.70
Bulk unit weight of sand - 17 kN/m3
A compacted fill of 2.5 m height with unit weight of 20 kN/m3 is placed at the ground level.
Correct : 37.5
