| 摘 要： | 桩的轴向承载力是由桩端阻力和桩侧摩阻力共同构成的。由于桩周土的性质千差万别给人们研究桩侧阻力的性状带来了很大困难。笔者在查阅国内外文献的基础上，根据对一些现场试验资料以及室内模型试验的分析，认为桩侧摩阻力存在着几种退化效应，即局部侧阻力随桩入土深度的增加发生退化、超过临界位移后侧阻出现退化现象以及在循环荷载作用下侧阻发生退化。

| Abstract: | The axial capacity of single pile includes point or base resistance and side resistance. The skin friction of pile shaft is not easy to determine because soils around pile is various. The analysis according to some papers indicates that side resistance decreases with the embeddment of the pile and the displacement of the pile after the soil reached the critic deformation. Cyclic loading on the pile reduce the side resistance also. |

| Keywords: | pile side resistance deterioration |
