Abstract: Bearing capacity of single pile is an essentia) part of foundation engineering field. The bearing capacity includes shaft friction along the pile shaft length and end-bearing capacity under the pile tip. The end-bearing capacity intensely depends on failure zone around the pile tip and it has been proposed by several authors. Failure zone has a shape of spherical cavity expansion is a remarkable proposal oil which this research focused. An analytical method based on cavity expansion theory was developed to determine the radius of failure zone under the piled tip for single pile in sand. Finite element method (FEM) was also used for comparing purpose. The radius of failure zone obtained from proposed method approximated to FEM. Results indicated that the radius of failure zone of single pile in sand can be determined using this proposed method.
