Help me solve please
A pile with a square cross-section, B × B = 0.5 m × 0.5 m, is driven in a clay soil which has an
undrained strength of 40 kPa at the ground surface, increasing thereafter by 3 kPa per meter
depth.
a) Determine the required length of an individual pile which is supposed to take a load of
500 kN on its top. Assume the factor of safety of 1.5 for both side shear and base resistance.
The side shear on the pile may be taken as 55% of the soil’s undrained strength
