where: qci = consolidation resistance
*α can be decided using table 20-4
Ab = end cross-sectional area of the pile
Ami = shaft area of the pile in contact with the soil.
should be ≥ 2.5 for piles in friction material
qcs = end resistance at the bottom of the pile within 4 ⋅ pile diameter from the end
of the pile

Example 5.2
Pile length 22 m, steel pile, friction pile, external diameter 200 mm, GC2,
Determine the ultimate bearing capacity of the pile
solution:
qc
Z↓ m( depth measured from ground MPa
