摘　　要：桩的负摩阻力的大小受多种因素的影响 ,故其准确数值很难计算。本文介绍了有效应力法 ,通过试验结果与计算结果的对比 ,得出有效应力法可以方便、准确地计算桩基的负摩阻力。The negative frictional resistance of pile is influenced by a lot of factors, so it is difficult to calculate the value of that. The article put forward the method of effective stress, and by using the contrast of the test and calculation come to the result that the negative frictional resistance can be got conveniently and exactly by the effective stress method.
