A 16 pile group, consisting of diameter concrete piles, were
cast in situ in a clayey soil whose unconfined compressive
strength is 1100 psf. Each pile is 60 ft long and the pile
spacing is 2.5 times the pile diameter.The water table is at
the ground surface and saturated unit weight of the clay is
118 lb/cu.ft. using a factor of safety 3 and a reduction
factor =0.45, compute the allowable capacity of the piles
acting as individuals
