Abstract: Skin friction of pile mainly depends on mechanical characteristics of surrounding soils, relative displacement on interface, lateral effective pressure, behavior of pile-soil interface, time effect, etc.. Based on the analysis of hyperbolic model of skin friction, the in-situ static test results of cast-in-place piles conducted in some places of Shanghai, are analyzed. Ranges of computational parameters related to hyperbolic model of skin friction are given. In addition, time-effect of skin friction of piles is also discussed briefly. Results show that it’s rational to illustrate the relationship between skin friction and relative displacement by hyperbolic function. In addition, due to time effect of pile displacement, lateral skin friction of pile indicates evident time-dependence.

Key words: cast-in-place pile, skin friction, hyperbolic function, time effect
