| 摘 要： | 针对静力压桩的特点，将沉桩过程中的侧摩阻力和端阻力分开计算，建立了一种新的计算模式，即球孔扩张-滑动摩擦模式。编制了计算程序，对桩端土按球形孔扩张计算；对桩侧土按滑动摩擦计算。算例证明，该计算模式是可行的。

| Abstract: | A new method to calculate penetration resistance of pressed-in piles, namely spherical cavity expansion-sliding friction model, is presented. The tip resistance and the side sliding friction resistance of pile are calculated respectively. A computer program, which can plot the calculating curves, is worked out. The calculating result shows that there is a good agreement between the calculated curves and the measured ones. |
