An experimental investigation for pullout response of a single granular pile anchor in clayey soil

Abstract The granular pile anchor foundation is an effective and economical foundation system to counter the pullout forces exerted in case of transmission towers or foundations in expansive soil. The pullout tests were performed to study the behaviour of a single granular pile anchor in the clayey...
