Theoretical Calculation of Negative Skin Friction for Pile Foundation in Layered Soil
In this paper, based on pile-soil interaction, the calculating method for the negative skin friction of pile in layered soil is proposed. Two load conditions, axial load on the top and overloading on soil around pile are presented, respectively. The transfer matrix method is used to analyze the first condition, while the soil consolidation theory and finite difference method are used to investigate the second condition numerically. The results can offer valuable references for both theoretical research and engineering design of long pile bearing larger negative skin friction.
