Shaft resistance of a pile embedded in rock
A rational calculation procedure is proposed for establishing the shaft resistance of a pile embedded in rock, based upon the Hoek and Brown failure model. The state of the art of the calculation of the pile shaft resistance is analysed. It is assumed that the horizontal stresses that are exerted upon the shaft in rock section are directly proportional to the vertical stresses. The coefficient of proportionality that represents the state of the pile-rock contact has a considerable effect upon the results obtained. A comparison is made between the results yielded and the different empirical theories that have been put forward with respect to this shaft resistance. It can generally be stated that the results obtained with this theory are reasonable for long and deeply socketed piles (high confining pressures) but the results are on the safe side in some cases where short piles (low confining pressures) are involved.
