Prediction of the performance of rock-socketed side-resistance-only piles using profiles

Abstract Various numerical techniques now exist to predict the performance of rock-socketed piles. These have generally ignored the influence of socket wall roughness on the pile capacity because no technique was available to include this effect. This paper examines the application of a simple model, which accounts for socket wall raoughness and provides a shearing mechanism at the pile-rock interface, to predict the performance of side-resistance-only piles socketed in weak rock. Good agreement was obtained between the predicted load-settlement response using the proposed technique and the actual results of 10 pile tests.
