Answer in three decimal places please
A square column foundation with base of
1.47 m is shown in the figure. It carries an
axial load of 488 kN and has its bottom
resting on the ground water table located h1
= 1.3 m. below the ground surface. h2 = 0.8
m and h3 = 2.6 m. Compute the effective
pressure at the mid-height of the clay layer in
KPa.

Soil Properties:
Unit Weight of Dry Sand= 15.6 KN/m3
Saturated Unit Weight of Sand = 19.5 KN/m3
Saturated Unit Weight of Clay = 18.7 KN/m3
Compression Index = 0.262
Swell Index = 1/5Cc
