Rock-socketed piles are used to transfer through shaft and base resistances the loads from a superstructure to competent rock layers. In many situations, rock-socketed piles are expected to behave linear elastically under working loads. In this paper, we present an elastic analysis that applies to piles with circular cross sections installed in rock layers. The analysis follows from the solution of the differential equations governing the displacements of the pile-rock system obtained using variational principles. The input parameters needed for the analysis are the pile geometry and the elastic constants of the rock and pile. A parametric study is used to illustrate the most important factors that need to be considered in the design of rock-socketed piles.
