【Abstract】 Based on the analysis of the uplift pile test data, the correlation of the adhesion factor versus the undrained shear strength of the soil around the uplift pile and the reduction factor of the skin friction between the uplift pile and the compression pile versus the slenderness ratio of the pile has been discussed in this paper in detail. The effects of soil behaviours and the pile type, etc. on the adhesion factor have also been studied. In addition, the prediction method of the pile’s uplift capacity is presented.更多还原
