Q3: Refer to the soil profile shown in the figure below: a) Calculate the variation in vertical stress, pore water pressure, and effective stress at points (A, D, B, and C). b) What is the change in the effective stress at the bottom of the clay layer if the water rises (Im) above the water table in the figure? c) How many meters must the water table rise (from the profile below) to decrease the effective stress by 10% at the bottom of the clay layer? A Sand 2m = 17.4 kN/m³ D W.T 3m 4m Ydry Yat 20.9 kN/m³ L B Clay Ysat 17,8 kN/m² C
