The analysis of load distribution in deep foundations found in dense and indiscrete sand between base and shaft is considered in this paper. The availability of designing deep foundations in sand with dilatancy was studied with changing dilatancy angle. For design, Plaxis 3D Foundation v2 Morh-Coulomb model was used. Various load distributions between shaft and base were obtained when dilatancy angle varied from 0° to 5°. Skin friction increases significantly increasing dilatancy angle. However, in Mohr-Coulomb model, (drained conditions) soil will continue to dilate as long as shear deformations occurs. This error decreases in case relative foundation length L/D and dilatancy angle ψ decrease.
