Answers to Tutorial questions 1 1. A single pile with the diameter of 0.5 m and is imbedded into clayey soils with depth of 6m. There are two layers of different soils. The upper layer of the soil is 2 meter thickness and its undrained strength is 30 kPa. The lower layer of the soil is 20 meter thickness and its undrained strength is 55 kPa. Estimate the ultimate bearing capacity of the pile. 2. Calculate the ultimate bearing capacity of a 10m pile with diameter 1.2 m driven into a soft clay. The unit weight of the pile 27 kN/M 3 and the saturated unit weight of

Unformatted text preview: the clay is 20kN/m 3 . The water table is 0.5 meter below the ground surface. The undrained shear strength of the soil varies with depth, as shown in the diagraph. 3. A single pile is designed to carry the load of 1200 kN in a deep soft clay foundation. The diameter of the pile selected is 1.2 meter. The soil is uniform with sat = 20 kN/M 3 , and its undrained shear strength is 60 kPa. A safety factor of 2.5 is required. Calculate the length of pile required.
