%X The stress and deformation of pile-earth/rock coupling system is a complex mechanics issue. In this paper, a model for the quick determination of pile’s side resistance is established based on continuous medium theory according to the deformation coordination condition (the deformations of soil/rock and pile differ by <i>n</i> times at the moment of separation between soil/rock and pile). The pile-soil/rock complex is considered as a layered material composing geologic materials with different stiffness. The research findings are as follows: (1) The side resistance of pile is manly affected by  <i>E</i><sub>s</sub>/<i>E</i><sub>p</sub>   the ratio of soil/rock’s elastic modulus to pile’s elastic modulus; the greater   <i>E</i><sub>s</sub>/<i>E</i><sub>p</sub> is, the more remarkable side resistance changes. (2) Side resistance of pile declines when the soil squeezing effect gets more evident. (3) The test dafa of the engineering test piles are verified by the rapid determination model for  pile foundation’s  side resistance. The results show that it is feasible and effective to use the model to predict the lateral resistance of similar pile foundations.
