Thirty-six piles, 0.6 m in diameter, are spread at 2.4 m centres in a 6 x 6 group. The piles extend between depths of 3 m and 18 m in a layer of stiff clay 28 m thick, overlying rock. The undrained shear strength of the clay at a depth of 18 m is 145 KN/m2 and the average value over the pile length is 105 KN/m2. The following parameters have also been determined for the clay: α = 0.4, A = 0.28, Eu = 65 MN/m2 and mv = 0.08 m2/MN. If the pile group carries a load of 21 MN, determine the load factor and the total settlement.
Its a group of 36 pile with a diameter of 0.6m
load factor is given by dividing load on the pile to safe load on pile
