Abstract

Several domestic and foreign design methods for rock socketed drilled shafts were introduced in this study. In order to verify these design methods, the results of field pile load tests were compared with predicted capacities using them. Based on this study, AASHTO(1996) and FHWA(1999) design methods tend to underestimate, and CFEM(2006) and NAVFAC(1982) tend to overestimate. The difference between the predicted and measured values was caused by reflecting different rock socket geometry and also different rock properties in each design method.
