How much load can safely be carried by a 20 m long, 0.3 x 0.3 m
square concrete pile driven in very stiff clay. Address the safe
load issue but not the settlement issue. Soil properties: su = 100
kPa, qc = 5 MPa, fc = 70 kPa, pL =
500 kPa, E0 = 7.5 MPa, Cc = 0.3,
cv = 10-4 cm2/s, γ = 18 kN/m3. If
you need additional properties assume reasonable values.
