Problem 7: The soil profile at the site consists of 5.0 m of silty sand underlain by 13 m of clay. The groundwater table is at a depth of 2.8 m below the ground surface. The silty sand has a unit weight of 19 kN/m3 above the groundwater table and 20 kN/m³ below. The clay has a unit weight of 15.7 kN/m³. Determine the depth of groundwater table from the ground surface to have an average effective stress at the clay layer of 100 kPa?

The soil profile at the site consists of 5.0 m of silty
sand underlain by 13 m of clay. The groundwater
table is at a depth of 2.8 m below the ground surface.
The silty sand has a unit weight of 19 kN/m3 above
the groundwater table and 20 kN/m³ below. The clay
has a unit weight of 15.7 kN/m³. Determine the depth
of groundwater table from the ground surface to have
an average effective stress at the clay layer of 100
kPa?
