A soil profi le consists of a clay layer underlain by a sandlayer, as shown in Figure P7.17. If a tube is inserted intothe bottom sand layer and the water level rises to 1 mabove the ground surface, determine the vertical effective stresses and porewater pressures at A, B, and C. IfKo is 0.5, determine the lateral effective and lateral totalstresses at A, B, and C. What is the value of the porewater pressure at A to cause the vertical effective stressthere to be zero?

Situation 3: 6. 7. 8. 9. 10. From the figure shown a soil formation with its corresponding soil properties and water table is located 2 m below the ground surface. To consolidate the ground, surcharge load at the top or dewatering are being considered. DRY SAND 2 m 4 m 18 m SAND CLAY Adry = 15.8 kN/m³ sat 19.1 kN/m³ Asat = 20.5 kN/m³ A decision has been made to consolidate the clay layer prior to site development by preloading with a sand layer 2.0 m thick. The sand fill will have a unit weight of 15 kN/m³. Find the increase in stress at the bottom of the clay layer. By dewatering 1.8 m, determine the stress increase at the bottom of the clay layer as water level is lowered down by 1.8 m. By how much should the water be lowered down to be more effective than the surcharge load?
