ANALYSIS OF BEHAVIOR OF EXPANSIVE SOIL FOUNDATIONS

The differential heave of foundation soil from moisture imbibition often causes major damage to overlying structures. Many methods have been proposed for estimating expansive soil heave, but there are no proven guide-lines for evaluating the behavior of foundations on swelling soils. Foundations built on expansive soils are often designed without considering the swelling properties of the soil, resulting in unsightly cracking or structural damage to the completed building. A practical method for evaluating the behavior of foundations on undisturbed expansive soil involves: a) a site study; b) laboratory on typical samples; c) prediction of the total and differential heave of the foundation soil beneath various types of foundations; d) choice of a suitable and economical foundation design.
