The soil profile at a building site consists of dense sand up to 2 m depth, normally loaded soft clay from 2 m to 6 m depth, and stiff impervious rock below 6 m depth. The ground- water table is at 0.40 m depth below ground level. The sand has a density of 18.5 kN/m³ above water table and 19 kN/m³ below it. For the clay, natural water content is 50%, liquid limit is 65% and grain specific gravity is 2.65. Calculate the probable ultimate settlement resulting from a uniformly distributed surface load of 40 kN/m² applied over an extensive area of the site.

Question
The soil profile at a building site consists of dense sand up to 2 m depth, normally loaded
soft clay from 2 m to 6 m depth, and stiff impervious rock below 6 m depth. The ground-
water table is at 0.40 m depth below ground level. The sand has a density of 18.5 kN/m³
above water table and 19 kN/m³ below it. For the clay, natural water content is 50%,
liquid limit is 65% and grain specific gravity is 2.65. Calculate the probable ultimate
settlement resulting from a uniformly distributed surface load of 40 kN/m² applied over
an extensive area of the site.
