The saturated unit weight of a 10 m thick clay layer is 20 kN/m3. Calculate the vertical effective stress at a depth of 5 m if the groundwater level is at the surface and select the correct answer from the below: O A. Total stress = 50 kPa Porewater pressure = 48.5 kPa Effective stress = 52.1 kPa O B. Total stress = 120 kPa Porewater pressure = 40 kPa Effective stress = 60 kPa O C. Total stress = 100 kPa Porewater pressure = 49.1 kPa Effective stress = 50.1 Pa O D. Total stress 110 kPa Porewater pressure = 42.2 kPa Effective stress = 55 kPa
Effective Stress in Soil Problem 1. The water table in a certain deposit of soil is at a depth of 2m below the ground surface. The soil consists of clay up to depth of 4m from the ground and below which lies sand. The clay soil is saturated even above the water table: Clay strata: ? = 30%,?? = 2.72 Sandy Strata: ? = 26%, ?? = 2.64 1. Compute the total pressure. 2. Compute the pore water pressure. 3. Compute the effective stress pressure at a depth of 8m below the ground surface
