Question
A square column foundation with base of
1.39 m is shown in the figure. It carries an
axial load of 481 kN and has its bottom
resting on the ground water table located
h1 = 1.5 m. below the ground surface. h2
= 0.7 m and h3 = 2.4 m. Compute the
average increase in pressure in KPa in the
clay layer below the center of foundation
using the 2:1
method.
