In Problem 10.7, determine the consolidation settlement under the corner of the mat.

Problem 10.7

A 15 m × 20 m mat foundation shown in Figure P10.7 carries a building load of 36 MN and is placed at 3.0 m depth below the ground level.

a. Find the net applied pressure on the underlying ground. The consolidation tests show that the preconsolidation pressure at the middle of the clay layer is 210 kN/m².

b. Is the clay overconsolidated?

c. What would be the consolidation settlement beneath the center of the mat?
