The figure shows a clay layer sandwiched between two sand layers: For upper sand and bottom sand stratum, y = 3.66 m, γ = 21.2 kN/m3. For compressible clay layer, Ho = 2.44 m, γ = 17.27 kN/m3, cc = 0.20, eo = 1.20The stress increase at the centre of clay is 28.8 kN/m2. The water table is deep. The settlement of clay is:

Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics for the solution of its respective engineering problems. (Source: Wikipedia)
