A fifteen-pile group (m = 5 and n = 3) consists of 0.35 m diameter friction pile is 10.0 m long with center to center spacing of 1.25 m. The piles are driven into clay with the following properties: Unit weight = 17 kN/m^3, qu = 150 kN/m^2, Nc = 9 and a = 0.8. 1. Compute the ultimate load bearing capacity of the group of piles considering the piles acts Individually. 2. Compute the ultimate load capacity if the piles in the group act as a block. 3. Determine the allowable load bearing capacity of the group of pile using a factor of safety of 3.0. 4. Determine the allowable load on the piles considering group action.
