PROBLEM 1: A layer of sand 4.5m thick with specific gravity of 2.60, degree of saturation of 85%, and porosity of 41.18% with a 5 m thick of clay with specific gravity of 2.65 and a water content of 0.28. Ground water table is located at the interface of the two soils. Compute the depth below the ground surfa would the effetive stress be 100kPa. B. Compute the effective stress at a depth 8m below the ground surface. C. Compute the depth of excavation required to reduce the effective stress by 60 kPa
