Question 1 (35 Points) A soil profile is provided below. The estimated stresses from a spread footing overlying a 10 meter thick normally consolidated clay layer are: 180.0 kN/sq m (top of the clay layer) 64.3 kN/sq m (bottom of the clay layer) 97.2 kN/sq m (middle of the clay layer) Estimate the primary settlement (in meters) of the clay layer assuming Cc=Cc/log(1+eo)= 0.44 and Cs' = Cs/log(1+eo) = 0.08 taken from consolidation curves. Assume the pre-consolidation pressure is 100 kN/sq m. Assume no settlement from the overlying sand layer. Depth 0 (GS) - 1 Y = 17.3 SAND * SAT = 19.81 KV/m 3 ELAY m -3 m 1
