摘要:
通过分析黄土湿陷引发的桩基负摩阻力的传递规律,基于荷载传递法建立桩侧摩阻力及桩端阻力的计算分析模型,对湿陷性黄土湿陷导致的桩基负摩阻力微分方程进行求解.据此得到了黄土地基不同湿陷阶段的桩基负摩阻力、桩身轴力及桩顶沉降的估算公式.研究成果可为黄土地基湿陷引发单桩负摩阻力的计算分析提供参考.
Abstract:
According to the transfer rules of the negative skin friction caused by the collapse deformation of the collapsed loess, analytical models of the negative skin friction and the pile tip resistance were established based on the load transfer method. Also, differential equation of the negative skin friction caused by the collapse deformation of the collapsed loess was worked out. As a result, estimation formula of the negative skin friction, axial stress and settlement of the pile in different collapse period was presented. Research results can serve as reference for the calculation and analysis of the negative skin friction of single pile caused by the collapse deformation of the collapsed loess
