| 摘 要： | 结合负摩擦力产生的机理，认为软土地区的桩基的负摩擦力问题主要是沉降问题，而不是强度问题。利用半理论半经验的桩基沉降计算方法［１］ ，对承受负摩擦力的桩基的中性点及桩基的沉降、桩的分担比进行简单的迭代计算，由此可确定承受负摩擦力的桩基的沉降，计算结果与实测结果的对比表明，该法简单可行。

| Abstract: | According to the m echanism of negative friction, it is show n thatsettlem ent ofpile foundation ism ore w orth considering than strength in soft soil area. On the basis of the sem i theoretical and sem i em pirical form ula of calculating settlem ent of pile foundation, settlem ent and location of neutral point andload sharing ratio of pile foundation w ith negative friction are all obtained by iterative m ethod. Com parisonbetw een calculated and m easured results show s that the m ethod presented in this paper is practical andfeasible to determ ine the settlem ent of pile foundation w ith negative friction, the values of negative frictionand load sharing ratio. |
