In Situ Stresses. Consider the soil profile shown in the figure below: (water unit weight 9.8 kN/m3) a) Calculate the total stress, pore-water pressure, and the effective stress at point B. b) Calculate the total stress, pore-water pressure, and the effective stress at point C c) How high should the groundwater table rise so that the effective stress at C is 111 kN/m2 Dry sand e 0.61 G, = 2.66 4 m Saturated sand e = 0.48 G 2.67 Clay sat 1 + e 1+e
