Upper Bound Solution for Pullout Capacity of Vertical Anchors in Sand Using Finite Elements and Limit Analysis
Publication: International Journal of Geomechanics
Volume 12, Issue 3
Abstract
The horizontal pullout capacity of vertical anchors embedded in sand has been determined by using an upper bound theorem of the limit analysis in combination with finite elements. The numerical results are presented in nondimensional form to determine the pullout resistance for various combinations of embedment ratio of the anchor (), internal friction angle () of sand, and the anchor-soil interface friction angle (). The pullout resistance increases with increases in the values of embedment ratio, friction angle of sand and anchor-soil interface friction angle. As compared to earlier reported solutions in literature, the present solution provides a better upper bound on the ultimate collapse load.
