= stress at the top of the pile
∴ The bearing capacity of the pile is 55.2kN
Now using the equation in (6-7), we will check the pile for failure
f Red = 22MPa (see section 5.6)
µ = 0.9
n
γ = 2.2
n
∴ =
In consideration of failure in the pile material, the pile can be loaded up to 9.0
MPa
In consideration of cohesion force, the pile can be loaded up to 55
MPa the bearing capacity of the pile is therefore, 55 MPa
