The nature of pile-rock interface has important influence on the pile-rock joint mechanical properties. A large number of engineering shows that the pile-rock interface has obvious shear rheological phenomenon. On the basis of displacement compatibility theory

the hyperbolic transfer function iterative calculation method is introduced

and an iterative method

which takes the rheological property of pile side rock into account to analyze the pile rock joint stress reaction

is established. The comparison of the iterative results and the site model pile test results shows that the hyperbolic transfer function iterative method can describe pile-rock joint mechanical properties accurately. Considering the pile rock interface shear rheology

the axial force throughout the pile grows gradually over time until it is stabilized. Pile axial forces are larger than that without considering the rheology. The iterative calculation results and the measured results are in a good agreement

which have certain reference value to the research of pile-rock joint mechanical properties.
