Helical piles are used as anchors to resist uplift, compressive forces and overturning moments in various civil engineering structures. Laboratory model tests were done on helical piles by varying the number of helixes (1, 2, and 3) and relative helical spacing ratio (0.67, 1.33) in medium stiff consistency clay. The vertical an oblique pulls were applied at an angle of 0 and 15 degree and the uplift capacity of each helical pile was determined. The pull with increase in the number of helixes, spacing between the helixes, embedment dep as well as the oblique while compared to that of oblique pull.
