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%
Pre-consolidation 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.
