Problem 2 A soil profile is shown Below. (a) Calculate the total stress, pore water pressure, and effective stress at points A, B, and C. (b) How high should the groundwater table rise so that the effective stress at point C is 104 kN/m 2 ? A Dry Sand e = 0.61 G s = 2.66 Groundwater table 4m B Saturated Sand e = 0.48 G s = 2.67 5m C Clay

Given radius of circular area, R = 3 m, and uniformly distributed load, q = 250 kN/m2, calculate the vertical stress increase, , at a point located 2.5 m below the ground surface (immediately below the center of the circular area). Problem 5 Refer to Figure 3. Given B = 4 m, q = 20kN/m2, x = 1.5 m, and z = 2 m, determine the vertical stress increase, , at a point A....
