Abstract: The characteristics of rock socketed pile is mainly decided by rock sockets. Based on shear expansion rule that is supposed to govern the pile-rock interaction, this paper uses load transfer theory to create a new load transfer function and generates a set of formulae suitable for soft rock socketed piles. Through analysis of these formulae and practical test results, it satisfactorily explained the relationship between pile-end resistance and socketed ratio H/D, investigated the effect of rock asperity and bottom quality, etc. on pile settlement and pile-end resistance, and also proposed some useful suggestions for socketed pile design.

Key words: socketed pile, load transfer behavior, shear expansion theory, socketed ratio
