Refer to Figure 11.40. Given: H = 5 ft, H, = 7 ft, H3 = 6 ft, and Ao = 3000 lb/ft. Also, Clay: e = 1.1, G, %3D %3D %3D = 2.72, LL = 45 %3D %3D Sand: e = 0.58, G, = 2.65 %3D

Define soil. Discuss the soil forming factors

A 5-ft fill is to be placed over the following soil profile shown below. Determine if the clay is normally consolidated or over-consolidated. The pre-consolidation pressure (past maximum consolidation stress) of the clay is 1000 lb/ft3. 5 ft 2 ft 4 ft Proposed Fill, y = 120 lb/ft³ Sand Clay Rock 2 ft A Ydry = 100 lb/ft³ Ground water table Ysat 110 lb/ft³ = o'= Pc = 1000 lb/ft²
