The side resistance of a bored pile in weak rock is heavily influenced by the roughness of the interface between the concrete of the pile and the surrounding rock mass. By observing the performance of such interfaces under carefully controlled laboratory conditions, and by progressively considering more realistic mechanisms of pile performance, an analytical model has been developed. This model appears to make acceptable predictions of the load-settlement characteristics of the side resistance and is used to produce some simplified design charts for peak load.
