The clay layer of 6 m thick is located under the gravel ground of 12 m thick. The water table lies 4m below the ground surface. It is because the bag is 0.30 for dry gravel floor, the dry unit volume weight is 16.2 kN / m3, the undrained shear strength for clay floor is 20 kPa, 24o for friction and 17.6 kN / m3 for saturated unit volume. According to doing; Based on the shear strength of the ground in the middle point of the clay layer, calculate the total and effective values of the stress acting on the vertical face of the ground element at the same point.
