摘要：A pile-soil interface model was established. The model considered the influence of interface lateral stress on the interface mechanics parameters. In this model the ultimate shear stress and the max tangential stiffness in loading process were related with pile lateral stress ratio. The influence of loading model on pile side resistance can be considered in this model. With the model, the interface parameters under pressing down at pile top can be got from those under pushing at pile bottom load. The suggested model was applied to analyze an O-cell pile test case. The analysis results show that the bearing capacity under loading press at pile top is higher than that under pushing at pile bottom, and the increase extent is agree with practical experience. It is also confirmed that the model is applicable and effective.
