| Rock-socketed piles have been extensively employed to receive and transmit a large concentrated load to deeper stronger materials. The side shear resistance of rock-socketed piles has usually been estimated through empirical formulations as a function of the uniaxial compressive strength of the intact rock (UCS). However, this approach neglects the influence of other important aspects such as the effect of roughness at the rock-pile interface. The aim of this work is to examine the socket roughness effect on side shear resistance of rock-socketed piles. To do that, PFC3D numerical models of rock-socketed piles with different degrees of socket roughness are employed. Numerical results are compared to empirical correlations proposed by different researchers. Finally, an empirical factor ?_(RF,1%) to side shear resistance prediction of rock-socketed piles is presented considering the socket roughness and the uniaxial compressive strength of the intact rock | |
