4. a) A group of 9 piles in a row is driven into soft clay extending from ground level
to a great depth. The diameter and depth of pile are 30 cm and 10 m
respectively. The unconfined compressive strength of clay is 70 kN/m2. If the
piles are placed 90 cm center to center, compute the allowable load on the
pile group, on the basis of shear failure criteria, for a factor of safety of 2.5.
Neglect the bearing at the tip of the piles. Take m = 0.6 for shear mobilization
around each pile. 10
