In this paper, the termination criteria of bored pile subjected to axial loading are predicted using numerical analysis. The objective of this study is to understand the influence of thickness and properties of overlay sand and characteristics of the founding rock strata. The software PLAXIS 3D Foundation 1.1 is used for the present numerical analysis. The axial loads on the pile are calculated as per IS 14593:1998. From the load–settlement curves, socket length for different thicknesses and densities of overlay sand and different types of rocks is predicted. Influence of pile diameter and interfacial shear strength on rock socket length is also examined. The predicted rock socket length is comparable with IS 14593:1998 recommendations. As the conclusions are from numerical analyses, result has to be verified with field test results and it is the future scope of this study.
