摘　　要：桩侧摩阻力退化效应可显著影响桩的承载力性状.文中总结了桩侧摩阻力存在退化效应的情况,分析了在沉桩过程中的桩侧摩阻力退化、循环荷载作用下桩土界面剪切疲劳退化效应产生的原因,并在桩侧摩阻力退化效应的情况下对桩的承载力计算方法进行总结和分析.The degradation of lateral friction resistance significantly affect the bearing capacity traits of pile founda-tions.The paper summarizes the existence of degradation effects on the lateral frictional resistance of piles.The causes of the degradation of pile lateral friction resistance during pile sinking and the shear fatigue degradation ef-fect at the pile-soil interface under cyclic loading are analyzed.The method of calculating the bearing capacity of piles in the case of degradation effect of pile lateral frictional resistance is summarized and analyzed.
