To consolidate the ground, surcharge load at the top or dewatering are being considered. DRY SAND 2 m 4 m 18 m SAND CLAY dry = 15.8 kN/m³ sat 19.1 kN/m³ sat = 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.
