Uplift Capacity of Pile Anchors in Cohesionless Soil
An analysis of uplift capacity of pile anchors in cohesionless soil is proposed in which Kötter's equation is employed to obtain the distribution of soil reaction on the axisymmetric failure surface, assumed to be the frustum of a cone with a characteristic angle of inclination with the pile-soil interface. A closed form solution for the uplift capacity of pile anchor is obtained with no requirement of any charts or tables. The results are compared with experimental data for a total 28 cases, ranging from loose to dense cohesionless soil, with maximum embedment ratio of 40, vis-à-vis available theoretical solutions. The proposed method leads to the predictions that are very close to the experimental results in 75% cases and this demonstrates the successful application of Kötter's equation for the estimation of the uplift capacity of pile anchors.
