Problem 3. A 4m thick of clay is overlain by 4m thick of sand. The ground water table is 1m below the natural grade line. Clay and sand have saturated unit weights of 19.5 and 17.3 kn/m³ respectively. Sand above the water retains water content of 30%. LL and void ratio of clay are respectively 60% and 27.3%. Specific gravity of sand solid is 2.7. 1. Find the compression index. 2. Find the moist unit weight of sand above the water table. 3. Find the effective soil pressure at mid clay layer.
