A 12 inch diameter circular concrete pile is driven at a site as shown in the figure below. Determine the 1. thicknesses of the clay layers (H and H2) if Qall 53.2 kips and the factor of safety is 2.0 Assume that pile bearing capacity has contributions from both the point and skin resistance. Use Myerhof's method to calculate bearing capacity of piles in clay to determine bearing capacity at the point. And use the alpha (?) method in calculating the skin resistance bearing capacity. Alpha values for layers 1&2 are given. Qal53.2 kips Saturated Clay layer 1 700 lb/ft 1 0.90 H-35 ft Saturated Clay layer 2 H2? 2000 lb/ft2 c" 2 0.56 12 inch diameter
