The load distribution and deformation of rock-socketed drilled shafts subjected to axial loads were evaluated by a load-transfer approach The emphasis was on quantifying the shear load transfer characteristics of rock-socketed drilled shafts based on constant normal stiffness (CNS) direct shear tests performed by varying major influencing factors. Based on the CNS tests and the Hoek-Brown failure criterion, a nonlinear triple curve was proposed for a shear load transfer function of rock-socketed drilled shafts. An analytical method that takes into account the soil coupling effect was developed. Through comparisons with results of load tests, it was found that the proposed function and analytical method in the present study are in good agreement with the general trend observed by in situ measurements.
