                                           = 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
