|Abstract: ||So many damages have been reported as a result of expansive soil. Such
damages occur when the pressure exerted by the soil is greater than the
foundation pressure. Consequently assessing the swelling pressure is an
important step in designing foundation on expansive soil.
Several researchers have developed an empirical relation for the estimation of
swelling pressure. The empirical expressions relate the swelling parameters to
the geotechnical parameters that are determined by the identification tests. But
the expressions should either be reformulated or checked for our local condition.
Therefore in this paper: the various equations already developed are tested for
the validity to our condition and new equations are developed that relates
swelling pressure with the index and physical properties.
The new formulas are developed, by taking one or more of the four parameters
(liquid limit, moisture content, dry density and plastic index) in different
combinations. The equations are developed by taking 14 samples and using
SPSS 9.0 for windows software. The equations are then tested for three control
samples. The most important equations are proposed, and conclusions and
recommendations are made|
