Abstract
The present study aims at determining the uplift capacity of axially loaded piles in clays whose undrained cohesion increases linearly with depth. With the application of the axisymmetric static limit analysis approach, proposed recently by the writers, the variation of the nondimensional uplift factors with respect to changes in the embedment ratio has been obtained for several rates of increase of soil cohesion with depth defined in terms of a nondimensional factor for given values of soil cohesion along the ground surface and diameter of pile. The uplift resistance has been evaluated in the form of the uplift factors, and due to the components of the shaft resistance and the total resistance, respectively. For the given values of and , the magnitude of the uplift resistance increases continuously with an increase in the value of . Furthermore, the values are found to remain unaffected with the variation in the shaft adhesion, whereas, the values increase continuously with an increase in the adhesion factor of the pile shaft.
