Abstract :
Existence of unsuitable soil for supporting
structures in construction sites, lack of space and
economic motivations are primary main reasons for
using soil improvement techniques with poor subgrade
soil conditions rather than deep foundation. Soil at a
construction site may not always be totally suitable for
supporting structures in its natural state. In such a case,
the soil needs to be improved to increase its bearing
capacity and decrease the expected settlement.
This topic gives an overview of techniques that are
commonly used to improve the performance, reduce the
post construction settlement, and enhance the shear
strength of the soil system, increase the bearing capacity
of the soil, and improve the stability of dams and
embankments.
Then, this study concluded that there is an urgent
need to study the technique of removal and replacement
for improving soil behavior taking into consideration
geotechnical requirements (i.e. bearing capacity and
settlement) and cost to achieve the optimum thickness of
replacement layers and the most suitable material
corresponding to minimum total cost of foundation
works.
