Abstract
Several structures resting on expansive soils suffer from severe distress due to their alternative swelling and shrinkage phenomenon. The above problem has really become a challenge to the geotechnical engineers in construction of foundations for different types of civil engineering structures resting on these soils. Numerous inventive foundation practices have been proposed for resisting the effect of uplift forces caused on the structure in poor clays. This paper highlights a pioneering practice to predict the behavior of granular pile anchor system against pullout forces in expansive soils. The water content is varied to 10%, 20% and 30% for different pile parameters. The various tests performed in laboratory showed that with the increase in length and diameter of the granular pile anchor system, the resistance against pullout forces increased. The highest pullout capacity is noticed at 20% water content.
