The soil profile and soil properties at a site are shown in the table below. A group of 12 concrete piles in a 3 × 4 matrix and of length 12 m is used to support a load. The pile diameter is 0.45 m and pile spacing is 1.5 m. Determine the allowable load capacity for a factor of safety of 2. Calculate the total settlement (elastic and consolidation) under the allowable load. Assume Ep = 20 × 106 kPa.
