(1a) A normally consolidated clay layer is 18 m thick. Natural water content is 45 %, saturated unit weight is 18 kN/m3, grain specific gravity is 2.7 and liquid limit is 63 %. The vertical stress increment at the center of clay layer due to foundation load is 9 kPa. Ground water table is at the surface. Determine the settlement.

(1a)
A normally consolidated clay layer is 18 m thick. Natural water content is 45 %, saturated unit weight is 18 kN/m3, grain specific gravity is 2.7 and liquid limit is 63 %. The vertical stress increment at the center of clay layer due to foundation load is 9 kPa. Ground water table is at the surface. Determine the settlement.
(1b) Estimate the settlement of a 10 m square area loaded 1 m at 100 kN/ m3 placed 1 m below ground level with ground water at the level of the footing. The static cone resistance values for the sand deposit are as follows: G.L to 6 m = 8000kN/m3,6 -11 mm = 10,000kN/, below 11 m =12,000kN/m3.
