摘　　要：基于传统的剪切位移法,建立了单桩工作特性的简化分析方法。该方法考虑了桩侧桩土接触面上的桩土相对位移,提出了一种新的描述桩侧剪应力与桩土相对位移关系的接触面模型。通过与试验数据的对比分析,验证了所提方法的可靠性。A simplified method based on the traditional shear displacement method is proposed for the working performance analysis of single pile.In this method,the relative displacement of pile and soil on the pile-soil interface is considered,and a new model of pile-soil interface is proposed to describe the relationship between the shear stress and the relative displacement of pile and soil.The proposed method is validated by comparing the predicted values with the experimental data collected from literatures.
