桩基负摩阻力形成机理及其计算

Forming principle and calculation of pile foundation negative friction

根据负摩阻力产生的原因,对负摩阻力形成机理进行了分析,结合《建筑桩基技术规范》提出了桩基负摩阻力计算公式,为带负摩阻力的桩基设计奠定了基础。

According to the cause of the negative friction,it analyzes the negative friction forming principle,combines with the Standards of the Construction Pile Foundation Technology,and gives the calculation equation of the pile foundation negative friction,so as to makes a foundation for the pile foundation design with the negative friction.
