The soil profile at a site for a proposed
office building consists of a layer of fine
sand 12.5 m thick above a layer of soft,
normally consolidated clay 1.5 m thick.
Below the soft clay is a deposit of
coarse sand. The groundwater table
was observed at 2.5 m below ground
level. The void ratio of the sand is 0.79
and the water content of the clay is
35%. The building will impose a vertical
stress increase of 250 kPa at the
middle of the clay layer. Determine the
primary consolidation of the clay (in
mm). Assume the soil above the water
table to be saturated,
= 0.27,
= 0.07, OCR = 2.9, and
2.75 *
The value must be a number
