A large cylindrical storage tank of radius 6 m with a flexible base rest on the surface of a deep layer ot ir clay, of shear modulus G-6+ 6z MPa, where z is the depth in meters below the clay surface. The ettective poisons ratio of the clay is 0.2.
A large cylindrical storage tank of radius 6 m with a flexible base rest on the surface of a deep layer of firm clay, of shear modulus G = 6 + 6z MPa, where z is the depth in meters below the clay surface. The effective poisons ratio of the clay is 0.2. The tank contains water to a depth of 7 m. By splitting the clay into three equal layers as far as the depth of influence, estimate the total 1-D oedometer settlement of the center of the footing. {12.5 Marks} technical
