1. A ten-story building is to be constructed at a site where the water table is close to the ground surface. The foundation of the building will be supported on 0.5 m diameter and of length 25 m concrete piles. The bottom of the pile cap will be at the ground level. The soil investigation at the site and laboratory tests have provided the saturated unit weights, the shear strength values under undrained conditions, and the soil profile of the soil. The soil profile and the other details are given in Table below. Required: a. Draw the soil-pile system. b. Determine the ultimate bearing capacity of a single pile.
