In a soil investigation for a construction project, two soil
types were identified with the following parameters (g = 9.81
m/s2):
Soil Type
Depth below ground level (m)
Unit weights (kN/m3)
Other parameters
Soil 1 (sand)
6.5
g = 17 and gsat = 17.5
E =15000 kN/m2
Soil 2 (overconsolidated clay)
11.5
gsat = 20
e0=0.69, Cc=0.25, Cs=0.05
If the ground water level is at 2.5 m below the ground level,
and the initial void ratio of the overconsolidated clay...
