Abstract:The anti uplift performances of pile are closely related to character of the contact surface. The correct selection of the mechanics parameters of contact surface has an important role in the analysis of the anti uplift theory of pile. According to the point surface contact model of pile soil contact surface and Coulomb's friction deformation principle, the value about the pile soil contact surface friction parameters are presented based on the test analysis of ten groups soil structure (steel, concrete) shear friction and conclude that the results will have important reference value for the correct value of pile soil contact surface mechanics parameters.
